Heating / cooling mode

In automatic operating modes, the temperature setpoints can be individually adjusted

for every comfort period and for the continuous operating modes. The temperature

setpoint of economy mode is the same in automatic and continuous operation.

In frost or overtemperature protection mode, the room temperature is constantly moni-

tored. If it falls (rises) below (above) the adjusted setpoint, control to the adjusted frost

or overtemperature protection setpoint will be ensured.

The controller generates the 24-hour operating mode from its current 24-hour program.

It automatically selects the switch-on time of the first heating / cooling period and the

switch-off time of the last heating / cooling period to generate and display a complete

heating / cooling period. The comfort setpoint used by the controller is the currently

stored standard setpoint of continuous operating mode . The self-generated 24-hour

operating mode is maintained until another operating mode is selected.

The switching program can be used as a 7-day or 24-hour program, depending on

programming. It is also possible to select one of the continuous operating modes

with which the switching program is not used.

With the 7-day program, all individual days, working days (1-5), weekend (6-7), or the

entire week (1-7) can be programmed.

For each heating / cooling period, 3 different switching patterns are available.

There is a choice of 1, 2 or 3 heating / cooling periods. For each heating / cooling pe-

riod, the start time, end time and comfort setpoint are to be entered.

In between heating / cooling periods, it is always the same economy temperature set-

point that is used. This economy temperature setpoint can be adjusted on the tempera-

ture menu.

The holiday function is to be selected on the user menu. Set the start of the holiday

period (day of departure / /weekday), the duration of the holiday period and

the temperature setpoint ( ). This will enable the controller to maintain the adjusted

temperature for a period of up to 99 days. Every day at midnight, the counter subtracts

one day.

When the holiday period is over, the counter reads 00, and the controller will automati-

cally resume the operating mode selected last.

To be flexible, the REV23RF has no connection facility for remote operation.

Heating engineer level

To access the heating engineer level, keep the «Warmer» and «Colder» buttons de-

pressed and simultaneously roll the roller selector away from the display and then to-

ward the display.

If the displayed temperature does not agree with the room temperature effectively

measured, the temperature sensor can be recalibrated (recalibration to be made on the

heating engineer level.)

The displayed temperature can be matched to the effective room temperature in incre-

ments of 0.2 °C (max. ± 2 °C).

Minimum setpoint limitation to 16 °C prevents undesired heat transfer to neighboring

apartments in buildings with several heating zones. The setting is to be made on the

heating engineer menu.

Optimization brings forward the switch-on point of the first heating period such that the

adjusted setpoint will be reached at the required time.

The setting depends on the type of controlled system, that is, on heat transmission

(type of piping system, radiators), building dynamics (building mass, insulation), and

heat output (boiler capacity, flow temperature).

REV23RF is a 2-position controller providing PID mode. The room temperature is con-

trolled by the cyclic switching of an actuating device.

The controller generates the positioning signals depending on the deviation of the set-

point from the actual value acquired by the built-in temperature sensor.

HVAC Products 09.10.2003

The rate of response to the deviation depends on the selected control algorithm:

The controller is supplied with an active self-learning mode, enabling it to automatically

adapt to the type of controlled system (building construction, type of radiators, size of

the rooms, etc.). After a certain learning period, the controller optimizes its parameters

and then operates with the parameters it has learned.

In exceptional cases, where the self-learning mode may not be ideal, it is possible to

select PID 12, PID 6 or 2-Pt mode:

PID 12 mode Switching cycle of 12 minutes for normal or slow controlled systems

(massive building structures, large spaces, cast-iron radiators, oil

burners).

PID 6 mode Switching cycle of 6 minutes for fast controlled systems (light building

structures, small spaces, plate radiators or convectors, gas burners).

2-Pt mode Pure 2-position control with a switching differential of 0.5 °C (±0.25 °C)

for very difficult controlled systems with considerable outdoor tempera-

ture variations.

Protects the pump against seizing during longer off periods. Periodic pump run is acti-

vated for one minute every 24 hours at midnight. This function can be selected on the

heating engineer menu.

(Caused by the smaller inductive switching load of the relay, we recommend to control

smaller inductive loads only, like smaller pumps.)

Periodic pump run active: / periodic pump run inactive:

The controller is suited for cooling applications.

The function can be selected on the heating engineer menu.

The controller comes set for heating operation (refer to section «Factory settings»).

User-defined data:

Press the button behind the pin opening for at least one second: This resets the user-

specific settings to their default values (heating engineer settings will not be changed).

The clock starts at 12:00. During the reset time, all sections of the display are lit, ena-

bling them to be checked.

All user-defined data plus the heating engineer settings:

Press the button behind the pin opening together with the warmer and colder buttons

for at least one second.

After the reset, all factory settings will be reloaded (also refer to section «Factory

settings»).

Mechanical design

The REV23RF has a plastic housing with a large display and easily accessible operat-

ing elements. The controller is removed from its base by sliding it upward. It is thus

possible to replace the two type AA 1.5 V alkaline batteries contained in the compart-

ment at the rear of the controller.

About 3 months before the batteries are exhausted, battery symbol appears on

the display, but all functions are fully maintained. When replacing the batteries, the

current data will be retained for a maximum of one minute.

Plastic housing with easily accessible operating elements and removable cover. The

unit can be fitted to all commercially available recessed conduit boxes or directly on the

wall. A relay with a potential free changeover contact, the connection terminals and the

receiving antenna are integrated in the housing.

The base can be fitted to most types of commercially available recessed conduit boxes

or directly on the wall.

The support supplied with the controller enables the unit to be put on a shelf. It can be

easily fitted to the controller with no need for tools.

Notes

• The room unit should be located in the main living room (on the wall or free-standing

using the support provided) while giving consideration to the following points:

• The distance to the receiver should not exceed 20 m or 2 floors

• The unit should be located such that the sensor is able to capture the room tempera-

ture as accurately as possible, without getting affected by direct solar radiation or

other heat or refrigeration sources (in the case of wall mounting, about 1.5 m above

the floor)

• The unit should be located such that it can transmit signals with as little interference

as possible. For this reason, the following points should be observed:

− Do not mount the unit on metal surfaces

− Not in the vicinity of electrical cables and equipment such as PCs, TV sets, mi-

crowave appliances, etc.

− Not in the vicinity of large metal structures or construction elements with fine

metal meshes like special glass or special concrete

• In the case of wall mounting, ensure that there is sufficient clearance for removing the

controller from its base, and for replacing it

Refer to the Installation Instructions printed on the package.

The receiver must be wired with the power supply switched off.

Mains voltage may be switched on again only after the unit is completely

mounted.

• When mounting the unit, the base must first be fitted and wired (L/N = AC 230 V

mains supply, LX/L1 = consumers). Then, engage the unit at the top, swing it down-

ward and secure it with a screw

• For more detailed information, refer to the Installation Instructions supplied with the

unit

For the electrical installation, the local safety regulations must be complied with.

It is recommended to first commission and switch on the receiver, then the transmitter.

• Switch on mains supply

a) Press the «Reset» button (= delete) for about 3 seconds, LED flashes for about 5

seconds (deleting the stored address)

b) Press «Set» button (= setting / learning) for about 1 second until the LED lights

c) The duration of the receiver’s learning readiness is a maximum of 25 minutes.

If no signal is received from the transmitter during that period of time, repeat

d) Mount transmitter and put it into operation

e) When the receiver receives a signal from the transmitter, the LED flashes briefly

f) When the LED is steady on, the relay is energized = controlled device ON

g) When the LED is dark, the relay is deenergized = controlled device OFF

h) In the event of a power failure at the receiver, the relay will automatically be de-

energized.

The transmitter repeats the ON or OFF signal at 20-minute intervals, depending

on the operating state. This means that the relay will be energized / deenergized

again after 20 minutes at the latest. This interval was selected to extend battery

life.

If the REV-R.02/16A receives no signal from the controller / transmitter for 60 minutes,

the relay will drop out so that the controlled device will automatically be switched off.

It is recommended to first commission the receiver and then the transmitter.
