Technical Description of IR 12 Heating Controller

IR 12 Heating Controller (ver. IR12_KRB) is a heating system controller. The controller can

handle up to 2 heating zones (one with a mixing valve, one unmixed with a return mixing

valve OR two mixed zones with no return mixing valve), DHW heating, DHW and space

heating by a fireplace, and a solar thermal system with 1-3 solar storage tanks. The

controller can be upgraded with an OpenTherm communication module and module for third

solar storage tank, universal output and two universal inputs for temperature sensors.

IR 12 Heating Controller is controlled by 6 keys. Information is shown on a 4-line display. The

Controller features 13 inputs for temperatures measured (by Pt 1000 temperature sensors)

and one input for Ripple control signal. Further it features 10 relay outputs (250V 3A) and two

triac outputs (250V 1A).

The Controller is fitted with an Ethernet interface enabling connection to a tablet, PC or from

a mobile phone. Servicing, firmware upgrade or elementary visualization of the concerned

heating system can be performed via this interface. The Controller also features an RS 232

communication interface. A gas boiler can be controlled from an OT (OpenTherm) module.

1. How to operate IR 12 Controller

The controller is operated using 6 keys , , , , C, OK on its front panel.

The DISP key switches between User and Service display.

Note: The Service display is intended to show info on the Controller itself and therefore it is

not needed during common operation.

The keys , are used to browse in the menu. In order to edit a parameter, press OK and

a cursor appears on the parameter. The values of numeric parameters can be

increased/decreased by pressing / keys. Selection parameters (e.g. ON/OFF) are

chosen by pressing keys , . When finished, pressing OK will move the cursor to the next

parameter in the same display. Parameter editing can be also exited without saving by

pressing the key C.

1.1 Basic User Menu

Pressing C in the basic User menu will always bring back the first – basic display.

1 – outdoor temperature

2 – weekday and time

3 – temperature in zone (if room temp. sensor is used) / heating water temp.

4 – temperature in Thermal Store

5 – temperature in DHW storage tank

Heating zone display (zone 1, zone 2):

1 – zone ON / OFF / NO (switched off in service menu)

2 – controller mode winter / summer (zone heating off)

3 – current room temperature. If no room sensor is used, the real temperature is shown as 0°C.

Temperature for zone 1 only.

4 – desired room temperature.

5 – adjustment to the desired room temperature. When RC21 IR room unit is used, “PJ“ appears

and the adjustment made by this unit is shown.

6 – desired heating water temperature for the zone

7 – current heating water temperature

The desired temperature can be changed by the user. If a room unit is used (for zone 1), the

temperature can be modified through this unit. Otherwise the desired temperature can be

adjusted via the parameter “adjust”.

Hot water zone display (DHW):

1 – hot water storage tank heating condition: ON / OFF / NO (switched off in service menu)

2 – current temperature in the hot water storage tank

3 – desired temperature in the hot water storage tank

4 – information if the tank is being charged by the boiler (heat / noheat)

Solar thermal system display:

1 – solar collector temperature

2 – system ON

3 – ON = solar pump running

4 – currently charged tank mark

5 – desired temp. for tanks when charged from solar

6 – current temp. in tanks

7 – hot water storage tank OFF

Fireplace display

1 – fireplace current flow temperature

2 – flue gas damper position (% open)

Boiler display:

1 – relative boiler modulation

2 – state of controller communication with boiler: comm (OK) / error

3 – desired flow temperature

4 – current flow temperature

Return heating water valve display:

1 – state of return water valve (absent – return water valve is not present; mixing – return water to

boiler is mixed from return heating water and preheated water in Thermal Store; toBoil – return

heating water is diverted directly into boiler; toThSt – return heating water is diverted into Thermal

Store for preheating)

2 – return heating water temperature

3 – Thermal Store water temperature

Firmware version and release date display:

Menu:

While in MENU, use arrow keys , to select user or service menu, or switch circulation on

immediately.

User Menu is intended to set zones, time schedules, OTC curve, date and time.

Add. Modules – this item will make available basic information on additional CIB modules (if

present).

UNI module universal module extending both inputs and outputs – absent/active (shows

whether the module is connected to PLC controller)

output state of the module’s universal output (a function adjustable on the service level)

t1, t2 temperatures at temperature sensors of the module

Service Menu is intended for more detailed adjustments to zones, sources, solar thermal

system and other parameters.

Access to the Service Menu is password protected and parameter adjustments are not

intended for laymen!

Immediate circulation is designed to switch DHW circulation immediately, with selected

parameters.

switch DHW circulation switched on immediately

circ.time how long the circulation will be on

2. User menu

User menu is comprised of:

•zone 1

•zone 2

•DHW zone

•DHW recircul.

•time program (time programs)

•OTC Curves

•operation data (temperatures and outputs condition)

•time, date

•other (adjusting other parameters)

•SMS settings (automatic text messaging)

•heat measurement (heat measured between two sensors)

The keys , enable browsing, and the selected item can be entered by pressing OK.

2.1 Heating zones

In this Menu, a user can adjust these parameters:

zone on switching on the zone on the User level. When a zone gets switched off on

this level, also the circulation pump and valve outlets switch off as well. The

pump and valve outlets can be activated by frost protection function if it is on.

In this controller version, switching off zone 1 will switch off zone 2 as well!

Mode Auto will activate the summer/winter mode.

T comfort setting comfort temperature in zone. This parameter makes sense only when

a room sensor is used.

T setback setting setback temperature in zone. This parameter makes sense only when

a room sensor is used.

Note: During a day, the controller switches the desired zone temperatures

between T day and T night by the preset time schedule.

setback setting heating water temperature reduction calculated from the OTC curve

when the mode changes from comfort to setback as preset by the time

schedule.

The Winter/Summer function is active if the zone is in Auto mode. The Controller will set the

zone temperatures by the parameters set. If the outdoor temperature equals or exceeds the

preset one for the specified number of hours, the zone will switch to Summer mode.

state shows the current mode. If the Winter/Summer function is turned off, Winter is

shown permanently here.

summer temp temperature threshold to switch to Summer mode.

summer time waiting time before switching to Summer mode.

winter temp temperature threshold to switch to Winter mode.

winter time waiting time before switching to Winter mode.

2.2 Setting temperatures for hot water storage tank

When there is demand for hot water storage tank to be heated up, the boiler is switched on

to max. output temperature, however no more than 70°C, and the DHW diverter valve is

shifted.

T comfort comfort temperature. Hot water storage tank gets heated up to this temperature if the

program is set to “Comfort” at the moment.
