I have radiator and underfloor heating zones. The underfloor heating zones are electric. Can tado° control my system?
Electric underfloor heating systems can only be controlled by tado° if the following conditions are met:
Also having same challenge, would love some pointers. Just want to know a system to get that I can retrospectively connect to tado.
How did this work out for you guys? Did you make any progress in your projects? Looking for same sort of solution, HomeKIT control of under floor heating. Any pointers greatly appreciated.
Did any of you guys find a solution to this? It seems like a simple problem...
DItto - I'd like to control just one room with electric UFH. It was suggested someone it would be possible via a relay, IE a tado sensor in front of a relay that is capable of switching in excess of 3amps.
May also need a separate independent floor probe in line as a safety cut off.
I have bought the Danfoss electric underfloor heating. It's less than 3A and does not require a probe.
I've got it to work, its relatively simple;
A Tado Wired Thermostat is used to trigger a Contactor (relay) which then powers the heating mat via a Manual Underfloor Heating Thermostat (which has the required floor probe).
i.e. Tado controls the room temperature, the Manual Thermostat prevents the floor overheating.
I use the very cheap, generic Underfloor Heating Manual Thermostats (they usually have just a dial, an on/off switch and a floor probe which acts as a thermal cut out). This Manual Thermostat only receives power from the Contactor when the Tado calls for heat. The Manual Thermostat is not intended to function as a roomstat, its sole purpose is to act as a floor probe safety cutout, so it is just set permanently to a maximum and is tucked out of sight. (You can buy more expensive Manual Thermostats which are designed to control the temperature of the floor, these can be used instead.)
Safety considerations: One isolator should switch off both the Tado Wired Thermostat and the heating mat supply; the Tado Wired Thermostat should then be protected by a 3A fuse; the Contactor's load side and heating mat should be protected by an appropriately sized fuse/breaker. RCD protection is required for bath/shower room wiring; Tado Wired Thermostats cannot be used in either bath/shower room Zones 1 or 2;
On the Tado App you might want to consider using the following settings:
Settings>SmartSchedule>[your room]>Settings>EarlyStartOn (as some mats take a long time to heat up, Tado will work out how long this needs to be)
Settings>OpenWindowDetection>[your room]>OpenWindowDetectionOff (as UFH is less responsive than radiators there may be no benefit in using this feature)
Home>Geofencing>Home (because radiators respond much quicker than UFH you might find there's not enough time for your UFH to come up to temperature with geofencing)
I hope this helps.
