Before you disconnect the wires and remove your 

existing thermostat, be sure this new thermostat, see the 

CT70 wiring hookup diagram, will replace it and that you 

understand how you will reconnect the wiring. To do that, 

proceed as follows:

Find the manufacturer of your heat pump in the Table of 

Contents, and turn to the appropriate page.

Expose the wiring on your existing thermostat (the 

subbase) and check that the terminals on your existing 

thermostat coincide with the terminals shown in the 

second column (Existing thermostat wiring). 

If they do, read and follow the installation instructions 

provided with the thermostat.

If they do not, call Honeywell Customer Assistance toll 

free at 1-800-468-1502, Monday-Friday, 7:00 a.m. - 5:30 

p.m. Central time, to be sure you can safely use this 

thermostat to control your heat pump.

Before you call, please have the following information 

available: thermostat model number and date code, heat 

pump model number and manufacturer, and number of 

wires connected to the thermostat. The date code is 

usually stamped on the back of the thermostat and is a 

four-digit number; for example, 9346.
