Question:
Connecting Dometic penguin /single zone to one touch system. Very familiar w single zone kits. Have installed more than 50. Looks like plug will have to be cut off to connect w one touch system in RV. There are no Dometic t stats involved here. It is hard wired into Dometic black box w cat 5 cable to control board operated by indoor touch pad

When wiring the thermostat and control box can the control box and thermostat share the same 12 hot. Can the red and red with white tracer both share the same 12 hot. Is the red with white tracer just to give 12 hot to the thermostat. Or is the red with white tracer another signal wire.

Can you use this thermostat to control two units? Both units are in an enclosed trailer and can be set to the same temperature. Would prefer to use a single thermostat instead of two separate thermostats. Thanks!
