ThermoSphere Dual Control Thermostat

£137.94 (inc VAT)

SKU: N/A Categories: ,


The ThermoSphere Dual Control Thermostat allows you to control an electrical heating appliance (such as a towel rail or mirror demister) in addition to your underfloor heating.  It features a UFH relay capacity of 16 Amps and the additional appliance relay capacity of 5 Amps.

Available in two colours – white or black.

The ThermoSphere Dual Control Thermostat is fully programmable – Flexible schedule options allow you to program 7 days separately, all 7 days the same or separate weekends.

The ThermoSphere Dual Control Thermostat features an open window sensor – this monitors the room temperature and switches the heating off if a door or window is opened. It also features a built in ambient temperature sensor and comes with an external floor temperature sensor. It is compatible with a wide range of popular floor sensor probes.

The ThermoSphere Dual Control Thermostat comes with one external floor sensor probe to install with your electric underfloor heating. You can also purchase an extra sensor probe to install at the same time, but leave disconnected – so that if the first probe should fail there is a backup that can easily be wired in.

The ThermoSphere Dual Control Thermostat also learns how long it takes your floor to heat up, and then optimises the start up time to ensure your room is warm when you want it to be.
