230V NTC Digital Weekly Programmable Popular Heating Gas Boiler HVAC Thermostat
C7 is a battery powered programmable room thermostat aimed at heating systems that need real setback rather than a single setpoint. It offers 7 day, 5/2 day and 24 hour schedules, a holiday mode for long absences and a manual override for one-off changes. Switching covers 24 V AC/DC up to 250 V AC at 50 Hz, 6 A with 2 A inductive load, so it suits both boiler relays and underfloor actuator circuits.
Key Benefits
- Three schedule modes let the same stat serve homes, offices and rental property
- Holiday mode drops the building to a holding temperature without losing the programme
- Keypad lockout stops unauthorised changes in shared and public spaces
- Factory pre-set programme means the unit works sensibly straight out of the box
- EL backlight and large push buttons keep it usable in a dark hallway
Problems It Solves
- Heating running at full setpoint in empty buildings
- Occupants changing settings in shared corridors and lobbies
- Complex programming that installers have to redo on a return visit
- Slab overshoot on underfloor systems controlled by a simple on-off dial

230V NTC Digital Weekly Programmable Popular Heating Gas Boiler HVAC Thermostat: Buyer Questions
What schedule modes does the C7 support?
7 day, 5/2 day and 24 hour. The mode is chosen during setup and can be changed later.
Can it drive an underfloor heating actuator?
Yes. The contact switches 6 A with 2 A inductive load across 24 V AC/DC to 250 V AC, which covers common actuator and zone valve loads.
How do we stop guests changing the programme?
Enable keypad lockout. The display keeps showing the room temperature but the buttons no longer alter the setting.
Does it hold the programme during a power cut?
The unit is battery powered, so the programme and clock are not lost when the heating supply is interrupted.
Which certifications apply?
RoHS, CE, CCC and ISO documentation. CCC matters if you are shipping into China, so tell us the destination when you enquire.
Can you preload our own default schedule?
Yes. Send us the weekday and weekend periods you want and we will set them before shipment.
