The Rinnai wall thermostat installation kit is for use with Rinnai Direct Vent Furnaces. It is an easy to install kit that connects to any thermostat - standard, 24V wired or WiFi enabled. When linked to a WiFi enabled thermostat, the kit allows for smart device control. If your wall thermostat is not WiFi enabled, that is fine - this kit will allow manual wall thermostat control as well.
This thermostat kit is compatible with all EnergySaver Direct Vent Wall Furnaces. These include both propane and natural gas furnaces EX08DT, EX11DT, EX17DT, EX22DT and EX38DT, as well as past models EX08CT, EX11CT, EX17CT, EX22CT and EX38CT.
