Honeywell Home TH401 Non-programmable Thermostat
About Your New Thermostat
This thermostat can be used to control an electric heating system such as a baseboard heater, a radiant floor, a radiant ceiling, a convector or a fan forced heater.
The thermostat CANNOT be used with:
- a resistive load under 0.83 A
- a resistive load over 10.4 A
- a system driven by a contactor or a relay (inductive load)
- a central heating system
SUPPLIED PARTS
- One (1) thermostat
- Two (2) 6-32 mounting screws
- Two (2) solderless connectors
Temperature Display and Setting
The thermostat normally displays the actual (ambient) temperature.
- To view the setpoint temperature, briefly press the Up or Down button. The setpoint will be displayed for 5 seconds and the screen illuminated for 12 seconds.
- To change the setpoint temperature, press the Up or Down button until the desired value is displayed.
Removing the Faceplate
TURN OFF POWER OF THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRIC SHOCK.
Loosen the screw holding the faceplate to the base. The screw cannot be completely removed and remains captive on the base. Remove the faceplate from the base by pulling the bottom half.
Wiring
Connect any one of thermostat wires to the heater (load) wire and the other one to the power supply wire using solderless connectors for copper wires. (The thermostat wires are nonpolarized; either wire can be connected to the load or to the power supply.)
2-wire installation
4-wire installation
NOTE: All cables and connections must conform to the local electrical code. Special CO/ALR solderless connectors must be used when connecting with aluminum conductors.
Installing the Faceplate
Install the base onto an electrical box.Reinstall the faceplate on the base and secure it in place with the screw.
NOTE: Keep the air vents of thermostat clean and unobstructed at all times.
