Hello Everyone, I was spending a couple of hours trying to connect with someone from Honeywell Resideo, to ask them specifics about their Hydronic zone control panels, but of course all their support lines have technical difficulties and not working. Thats when I found this incredible forum and thought I give it a shot and see if someone can help me out. Here is our (Probably quite unusual and specific problem 
We have a retrofitted home with trench heaters (Which a pretty much hydronic fantail units that are embedded in your floor) and are about to wire the fantail thermostats to our Honeywell zone control board in order to open the actuator valves on our manifold if the thermostats call for heat. This is of course all very simpel and nothing unusual, besides that fact that these thermostats are usually used to drive the actuators themselves, basically sending a 24V AC/DC signal when calling for heat. But of course the zone panel has the usual R/W/C connectors for a normal thermostat to just close the loop when calling for heat and not supplying power to these connectors (At least that's what I am guessing - I am not sure how these regular thermostats operate and or supply the signal to turn on power to the actuators. Well, my question is, if anyone has experience as to how we could connect our fantail thermostats (Model is Siemens RDG160TU) to the Honeywell Zone control board (HPZC106). Also, because the trench heaters are running on DC power in order to run the modulating fans, the thermostats are as well powered by the 24V DC power supply, so the power the Thermostat outputs when calling for heat is 24V DC. Is it at all possible to connect these specific thermostats to the Honeywell HPZC106 ?? Any help or knowledge would be much appreciated. Best, Peter
