Can I create a separate heating zone for my annexe?

Yes, with Wiser you can set up a zone for your annex with Wiser Radiator Thermostats (1st or 2nd Generation) or a Wiser Room Thermostat. The Wiser Plug is also available to extend the range.

NOTE: If the annexe is fed from the same channel as the main house a Radiator Thermostat may be the preferred option for control. Using only a Room Thermostat with traditional Radiator Thermostat will result in the annexe heating whenever this boiler channel is active as there is no automatic action to close the radiator valve.
