0-10V Infratech heater with TVMs
We had this question from a customer and though it would be worth sharing it.
We have a HomeWorks system that we need to add controls for Infratech heaters that need 0-10v control. The heater loads will not be on HomeWorks but on a separate Infratech control system. All HomeWorks needs to provide is 0-10v signal to the Infratech control panel to turn on/off and dim the heaters. There are four separate dimming control zones at house.
Can I put a TVM-KIT and a couple TVM2's in a PNL-8 with a RPM-4u to get the proper 0-10v signal to send to Infratech controls? I won't need to RPM-4U to control the loads but I think I need RPM-4U to assign the heater switch legs into the system. Will this work without heater loads being connected to RPM-4U? Do I need to provide 10v transformer for 10v source or does the TVM2 provide 10v source?
