Can I connect multiple power modules to a single Schluter DITRA-HEAT-E-RS1 thermostat?

Yes, you can connect multiple power modules to a single Schluter DITRA-HEAT-E-RS1 Smart Thermostat. The system allows for up to 10 power modules to be connected to one thermostat. Here's how to do it: First, use 20 AWG signal or communication wire rated for 300 volts (CL2/CL3 or CM in the USA, and CMG/FT4 in Canada). Connect AUX 1 & 2 on the thermostat to the AUX IN on the first power module. Then, link the AUX OUT of the first power module to the AUX IN of the next power module, and continue this daisy-chain setup for additional modules. The wiring connections do not have polarity, so you don't need to worry about the wire orientation. Secure each power module to the electrical junction box with the provided screws. After all modules are connected, replace the covers and tighten the screws. Finally, power up both the power modules and the thermostat.
