FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
This thermostat is designed to control a heat pump system where automatic changeover is not required. The thermostat is equipped with EMER HEAT and AUX indicator lights. The EMER HEAT indicator light can be wired to a malfunction switch in the system to provide a malfunction indicator.
If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor, electrician, or someone famil- iar with basic electricity and wiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and ordinances.
This control is a precision instrument, and should be handled carefully. Rough handling or distorting compo- nents could cause the control to malfunction.
PRECAUTIONS
!CAUTION
To prevent electrical shock and/or equipment damage, disconnect electric power to system, at main fuse or circuit breaker box, until installation is complete.
!WARNING
Do not use on circuits exceeding 30 volts. Higher voltage will damage control and could cause shock or fire hazard.
DO NOT USE this thermostat on heat pump sys- tems that have a spark ignition gas or fossil fuel second stage heat source.
