With a 24 V transformer (except the R841D1036 w/o a transformer)
Compatible with the T822K1034, T87K1015 and ET180 thermostats (the R841D1036 w/o a transformer is also compatible with the STE241 and D010 thermostats)
Installing more than four relays without a transformer to the same thermostat is not recommended (two relays without a transformer if connected to a STE241 thermostat)
