Optima W PLUS is a development of DIHS BV, NETHERLANDS. www.dihsbv.nl

This surface-mounted radio thermostat has been developed to be able to switch electric and

conventional heating systems on and off using a set temperature and time. It can pair with TC-25, TC30,

TC35, TC40 or TC-60 for remote control anytime anywhere.

Functions

Large display can be clearly read with the background lighting.

Easy to fit thermostat and receiver.

Five buttons make it easy to use.

4 periods of each day programmable

The display shows the set temperature as well as the measured temperature, time.

Temperature display in degrees Celsius.

The thermostat is supplied with a wall-fixing frame, base and a very compact receiver

(surface-mounted).

Parameter Settings Explained

Feature 01– This feature used to calibrate the room temperature when need. For example, if actual

room temperature 21.5°C, but thermostat shows 23°C, then you can set this value to -1.5 to calibrate.

Feature 02/03– Temperature Max.& Min. Limit: This function allows you to limit the use of the up and

down temperature by pressing +/- buttons.

Menu 05 - Low Temperature Protection: This is the temperature maintained when the thermostat is in

Frost Mode. If room temperature below 5°C(Settable), thermostat will turn on heating device till room

temperature arrive 5°C(Settable).

Menu 09 - Switching Differential: This function allows you to increase the switching differential of the

thermostat. The default is 0°C which means that with a set temperature of 20°C, the thermostat will

switch the heating on at 19.5°C and off at 20.5°C. With a 0.5°C differential, the heating will switch on at

19°C and off at 21°C.

Menu 11– This feature used to lock the keys. When lock, you can long press SET button to unlock.

Menu 12-This function allows you to save energy. When enable Open Window Detection function, the

system will automatically stop heating when it detects a sudden drop of room temperature (2°C in 15

minutes as default). This is normally caused when a window or door is opened without turning off the

heating device.

The device will return to the previous mode of operation after 30mins, then letter OP disappear. Press

any button will exit OWD function during the heating off period.

Menu 13-The setting time to detect the drop of room temperature between 2-15mins (15 mins is the

default setting).

Menu 14-The drop temperature to during detect period. Setting between 2-4°C (2°C is the default

setting).

Menu 15-The time to exit OWD mode select. Setting between 10~60min(30min is the default setting).

Installation

Mount the thermostat at eye level. Read the instructions fully so you get the best from our product. Do

not install near to a direct heat source as this will affect functionality. Do not push hard on the LCD

screen as this may cause irreparable damage.

Step 1: Carefully separate the front half from the back plate.

Step 2: Screw the thermostat back plate securely on wall with provided screws

Step 3: Clip the front of the thermostat onto the back plate.

TC-25 TC-30:

Step 1: Using a small screwdriver, slightly loosen receiver cover plate.

Step 2: Terminate the thermostat as shown in the diagram

Step 3: Clip the front of the thermostat onto the back plate.

Types of receivers (with RF and WiFi);

TC-25: Wall mounted receiver, 230Vac, voltfree output, 10 A Ohmic load / 4A Cap/ind load.

TC-30: Wall mounted receiver with floorsensor, 230Vac, voltfree output, 10 A Ohmic load / 4A Cap/ind

Load.

TC-35: Flush mounted receiver, 230Vac, voltfree output, 16 A Ohmic load / 10A Cap/ind load.

TC-40: Flush mounted receiver with floorsensor, 230Vac, voltfree output, 16 A Ohmic load / 10A

Cap/ind Load.

TC-60: Plugin mounted receiver, 230Vac, powered output, 16 A Ohmic load / 10A Cap/ind load.

NOTE;

When the voltage output is above 230Vac, eg 240-250Vac, then the capacity of the receiver should be

lower. For the TC-25 and TC-30 the maximum ohmic load is then 6A. For the TC-35, TC-40 and TC-60

its 12A ohmic load.
