The COMPUTHERM E280 Wi-Fi Thermostat allows you to control connected heating or cooling devices, such as boilers or air conditioning systems, via your smartphone or tablet over the internet. This thermostat is compatible with any two-wire thermostatic connector and supports both 24V and 230V control circuits. It is particularly useful for managing heating/cooling in homes, apartments, or holiday residences, especially when occupancy schedules are irregular.
Equipped with a connectable floor temperature sensor, the E280 is ideal for controlling underfloor heating systems. It features two potential-free relays that can operate simultaneously, allowing independent control of two devices. This enables the thermostat to manage a pump and a zone valve in addition to the main boiler, facilitating multi-zone heating systems without requiring a separate zone control system.

- Power Supply (L, N): Connect the live (L) and neutral (N) wires of your 230V AC power supply.
- Relay K1 (COM, NO, NC): This relay is typically used for controlling the main heating/cooling device (e.g., boiler).
- COM: Common terminal.
- Mba: Normally Open (connect to this for heating applications where the circuit closes to activate).
- NC: Normally Closed (connect to this for cooling applications where the circuit opens to activate).
- Relay K2 (COM, NO): This relay can be used for an auxiliary device, such as a pump or zone valve.
- COM: Common terminal.
- Mba: Na-emepe emepe.
- Ihe mmetụta ala: Connect the wires from the external floor temperature sensor to the designated terminals.
3. Mgbakọ ikpeazụ
- Once wiring is complete and secure, carefully reattach the front panel of the thermostat to the backplate.
- Restore power to the system. The thermostat display should illuminate.
