Only the remote thermostat transmitter senses temperature.
The room the remote/transmitter thermostat is installed should have its TRV head removed to fully open the valve permanently.
Once the set temperature is reached, I believe this will turn the boiler off (as it is on off control). At that point does it just turn off boiler completely, or will it go into a mode where radiators can stay turned off and I can still get hot water to kitchen and bathroom (similar to summer mode) ?
It will only switch off the heating. The hot water will not be affected.
It does sound like a new one is needed.
Yes, both are included.
As long as the boiler accepts normal on/off heating controls. The boiler manufacturer will confirm.
I'm afraid not.
It is protect your house from frost (burst pipes). I would recommend 5C.
You can change the temperature displayed by changing option 2-04 in the installers menu (see installation instructions). During auto mode you can press the i button to see the other temperature.
If it is a combi boiler, it just wires to the thermostat terminals as well as the live and neutral terminals.
The included receiver is not suitable for electric radiators. So you would have to buy the transmitter and receivers separately, please email us at firstname.lastname@example.org with how many receivers you require and we will get a price for you.
It is 868Mhz. It should be at least 1.5m away from other wireless devices.
Yes it is.
Turn the dial to the power position. Press the I button for 5 seconds Press the 2 button to enter the installer menu Press OK several times to get to menu 2-07 Use the + button to change it to 365 days (or amount of days until the next service) Press OK Turn the dial to auto to exit the installer menu and return to programme
You can press the top button to override it to comfort mode.
