Honeywell TH3110D1008 Non-Programmable Thermostat

Product Information

The Non-Programmable Digital Thermostat is part of the PRO 3000 Series, available in two models: TH3110D1008 and TH3210D1004. It is designed for easy installation and operation.

Installation Instructions

1. Start by removing the wallplate from the thermostat by pulling it from the bottom.
2. Pull the wires through the wire hole.
3. Position the wallplate on the wall and use a level to ensure it is straight. Mark the hole positions with a pencil.

Display is blank

• Check circuit breaker and reset if necessary.
• Make sure power switch at heating & cooling system is on.
• Make sure furnace door is closed securely.
• Make sure fresh AA alkaline batteries are correctly installed (see page 2).

Heating or cooling system does not respond

• Set system switch to Heat. Make sure the temperature is set higher than the Inside temperature.
• Set system switch to Cool. Make sure the temperature is set lower than the Inside temperature.
• Wait 5 minutes for the system to respond.

Temperature settings do not change
Make sure heating and cooling temperatures are set to acceptable ranges:
