Hi,
I received some advice on another thread about heating for my house and I have a follow up question that I hope you can help with.
I would like to setup my house with 2 central heating zones (upstairs and down) using Vaillant VRC430, VR61 and VR81. If we use the VR81 to control the upstairs temperature, would this upstairs zone be using the weather compensator device and be modulating or would this zone be controlled by the zone being turned on-off?
The VR61 manual mentions having the ability to be setup to have 1 controlled and 1 uncontrolled heating zone. Does the controlled zone mean modulating and the uncontrolled mean on/off temperature control?
BTW, will have a unistor cylinder as well, not sure if this is relevant to the above.
Thanks.
