INSTALLATION INSTRUCTIONS
Interior Mounting Base
For applications where the wire run is short (100 ft. or
less) shielded cable may not be required provided the
wires are not routed parallel to or across other wires
carrying electrical power. To reduce electrical inter-
ference or inductance from other electrical wiring or
devices use shielded cable and keep Remote Sensor
wire runs separate from thermostat wiring. Remote
sensors cannot be used with systems where power
interruptions are part of normal system operation.
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
Do not use on circuits exceeding specified
voltage. Higher voltage will damage control
and could cause shock or fire hazard.
Do not short out terminals on gas valve or
primary control to test. Short or incorrect
wiring will damage thermostat and could cause
personal injury and/or property damage.
