I have a new fan powered humidifier (Carrier LFP 1418, I think same as last years 1318) and a RiteTemp 8085C thermostat. The thermostat has the capability to control the humidity.
The humidifier has two wires (both brown) and a sticker on them that states "Caution Do not connect these leads to line voltage" and a standard 110 plug.
Instructions from the RiteTemp:
Connect the humidifier control wire to the H terminal on the new RiteTemp thermostat.
The humidifier instructions:
Shows both leads going to a 24V coil normally open relay (part HN61KQ120) the other two leads on the relay connect to the C and HUM on the ‘Thermidistat Control’.
My question is how do I connect this properly, I want to just use the RiteTemp thermostat to control the humidifier and not the supplied manual humidistat? Do I need the relay that is described in the instructions for the humidifier? Is this relay needed if a 'Thermidistat Control' is being used but not with a different kind of thermostat.
