Yes, the Schluter Systems DITRA-HEAT-E-RS1 Smart Thermostat supports the connection of multiple power modules. You can connect up to ten power modules to a single thermostat. Here's how to do it:
- Use 20 AWG signal or communication wire rated at 300 volts (CL2/CL3 or CM for the USA and CMG/FT4 for Canada).
- Connect from AUX 1 & 2 on the thermostat to the AUX IN on the first power module.
- Connect AUX OUT from the first power module to the AUX IN of the next power module, and continue this daisy-chain method for all subsequent modules.
- Wiring polarity does not matter; there is no need to worry about wire orientation.
- Secure each power module to the electrical junction box using the provided screws.
- Once all power modules are connected, replace their covers and tighten the screws.
- Power on both the power modules and the thermostat. This setup allows you to expand the heating capacity controlled by a single Schluter DITRA-HEAT-E-RS1 Smart Thermostat.
