What is a Room Thermostat?

If your heating system is a boiler with radiators, there will usually be only one room

thermostat to control the whole house. But you can have dierent temperatures

in individual rooms by installing thermostatic radiator valves (TRVs) on individual

radiators.

If you don’t have TRVs, you should choose a temperature that is reasonable for the

whole house. If you do have TRVs, you can choose a slightly higher setting to make

sure that even the coldest room is comfortable, then prevent any overheating in other

rooms by adjusting the TRVs.

Room thermostats need a free ow of air to sense the temperature, so they must not

be covered by curtains or blocked by furniture. Nearby electric res, televisions, wall

or table lamps may also prevent the thermostat from working properly.

A room thermostat simply switches the heating system on and o as necessary.

It works by sensing the air temperature, switching on the heating when the air

temperature falls below the thermostat setting, and switching it o once this set

temperature has been reached.

Setting a room thermostat to a higher temperature will not make the room heat up

any faster. How quickly the room heats up depends on the design & size of the heating

system.

Similarly reducing the temperature setting does not aect how quickly the room cools

down. Setting a room thermostat to a lower temperature will result in the room being

controlled at a lower temperature, and saves energy.

The way to set and use your room thermostat is to nd the lowest temperature settings

that you are comfortable with, and then leave it alone to do its job.

The best way to do this is to set the room thermostat to a low temperature

– say 18°C , and then turn it up by 1°C each day until you are comfortable with the

temperature. You won’t have to adjust the thermostat further. Any adjustment above

this setting will waste energy and cost you more money.

To pair the thermostat with the RC1-WTS receiver, follow these steps.

On the receiver;

Press the Pair button once.

The Communication LED will light up.

On the thermostat;

• Press PROG and then SETUP ...................................................................................

• At the top of the LCD, you will see 01.

• Use the Up key to select 05 and enter the pairing function .....................................

• Press Zone 1 or Zone 2 to select the relevant zone .......................................

(Two DT-WTS can work with a single receiver, oering a two zone system)

• In the centre of the LCD, you will see 01. This is the channel address.

The default setting of 01 can be used in most cases, but should be changed when

a conict is detected with other RF devices.

• Use the Up/Down keys to enter the address ......................................................

• Press SETUP to Pair the thermostat and receiver ........................................................

Note: You must nish pairing the thermostat before the communication LED goes out.

Pairing the Thermostat Pair Successful

The Comms LED on the receiver should ash and then go out to indicate

the pair is successful. The thermostat will display the communication icon.

Pair Fail

If the Comms LED does not ash there is a problem with the RF signal and

you should reduce the distance between the thermostat and receiver.

Where possible ensure there are no metal objects blocking the signal.

The LED will automatically go out after 1 minute.

Room Temperature SET Temperature

Temperature Display

The temperature display information is driven by two dierent inputs; the sensor

measurement and the target temperature you have set.

This is the current room temperature. This is the temperature you are trying to

achieve in your home.

Keypad Lock Indicator

Locking the Keypad

The thermostat has a keypad lock facility.

• To activate the lock press the bottom right corner of the display and hold for 10s.

• When activated, you will see the Keypad Lock symbol.

• To cancel, press the bottom right corner of the display again for 10 secs.

Clean Screen

Pressing will disable all keys, providing you 15 seconds to wipe the screen

clean before the keys are re-activated.

Pressing the key once will place the thermostat in frost protect mode.

In this mode, the thermostat will display the frost icon and will only turn the heating on

should the room temperature drop below the set frost temperature (see page 16).

Should the heating be turned on whilst in frost mode, the ame symbol will be

displayed.

To cancel the frost protect mode, press the key once.

THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES

NEED NOT BE ADJUSTED

Feature 01 – Temperature Format: This function allows you to select between °C or °F.

Feature 02 - Switching Dierential: This function allows you to increase the switching

dierential of the thermostat. The default is 1°C which means the thermostat will

switch the heating on 1°C below the set temperature and will turn it o when the set

temperature is achieved. With a 2°C dierential, the heating will switch on 2°C below the

set temperature and will switch o when the set temperature is achieved.

Feature 03 – Frost Protect Temperature: This is the temperature maintained when the

thermostat is in frost mode. The range is 07-17°C. The default is 12°C and is suitable for

most applications.

Feature 04 – Output Delay: To prevent rapid switching, an output delay can be entered.

This can be set from 00 - 15 minutes. The default is 00 which means there is no delay.

Feature 05 – Pairing Function: Allows the thermostat to be paired with the receiver.

Feature 06 - Fail Safe: If enabled, the thermostat will send a signal to the receiver every

20 minutes. Should the receiver fail to receive the signal from the thermostat, the receiver

will activate the output for 20% of the time. This is to protect the system against a loss of

wireless signal or in case the thermostat battery fails whilst you are away.

Optional Features Explained

The heating is indicated ON when the ame icon is displayed.

When the ame icon is absent, there is no requirement for heating to achieve the set

temperature but the thermostat remains active.

To turn the thermostat OFF completely, press and hold the Power key ..................

The display and heating output will be turned o completely.

To turn the thermostat back ON, press the Power key once .........................................
