Hi all,

I am a complete noob when it comes to central heating so apologies if this question seems silly.

We have a 3 floor house, with a Honeywell DT200 digital room thermostat in the master bedroom on the 2nd floor and another DT200 on the ground floor (in the hallway). We also have a Honeywell ST6400C Programmer which has a control for heating and a control for hot water.

As we have 2 room thermostats, I thought that the heating system was split into two zones however as there aren't 3 controls on the controller (literally just CH and HW) I am no longer sure. When I look where the tank is, I can see 3 valves, 1 for the CH and I assume 1 each for the two thermostats.

So, is it possible for any of you more knowledgeable people to confirm whether we a two zone heating system and whether the Tado system will be able to work with our setup?
