|---|---|---|
| Thermostat display is blank | Batteries exhausted, installed incorrectly or tab hasn't been removed Battery power critically low | Pull thermostat from wall bracket or table stand and check battery installation, replace batteries if necessary |
| Display = — | Faulty temperature sensor Boiler (water) already at temperature | Replace thermostat or check wiring to remote temperature sensor if fitted Normal behaviour - wait for water temperature to drop |
| Thermostat shows heat demand but boiler doesn't respond | Faulty wiring connection | Check wiring at thermostat and boiler terminals |
| Thermostat display shows — and Receiver Box ? LED is flashing RED | Wireless communication with Receiver Box is lost | Move thermostat to a location where wireless communication is reliable |
