Frequently Asked Questions
Is the E901 compatible with my boiler?
Yes — works with any gas, oil, or LPG boiler with a standard volt-free thermostat input. Also suitable for on/off heat pumps.
Does it require mains power?
No — the thermostat runs on batteries; only the relay output is wired to the boiler.
What's the difference between the E901 and E901-WIFI?
The E901 is wired without smart features; the E901-WIFI adds wireless RF and app control. For basic programmable control, choose E901.
Does it support OpenTherm?
No — uses volt-free on/off control. For modulating control, a dedicated OpenTherm thermostat is needed.
What's in the Box
- 1× E901 thermostat (battery-powered)
- Wall fixings
- Full instruction manual
Note: 2×AA batteries not included.
