APPENDIX 1 – SPECIAL CONSIDERATIONS FOR INSTALLING THE MODEL 8800 WITH

THE 8870 COMMUNICATING THERMOSTAT

WARNING

WHEN REPLACING AN 8870 THERMOSTAT WITH THE MODEL 8800 THERMOSTAT THESE ADDITIONAL STEPS ARE REQUIRED

IN ORDER FOR PROPER OPERATION.

1. The 8800 Thermostat cannot be powered from an 8818 Distribution Panel. The 8800 Thermostat must be powered from a

separate 24VAC transformer.

2. The Model 8800 thermostat must be set to non-programmable mode to be used in a 8870/8818 system.

3. Replace any 8061 TT Support Modules connected to the thermostat with 8081 TT Support Modules, but in cases where a

single ﬂush mount and/or outdoor sensor is used they can be directly connected to the new 8800 Thermostat and the Support

Module can be eliminated.

4. Replace any 8062 TrH Support Modules connected to the thermostat with 8082 TrH Support Modules.
