POWER INPUT WIRING
WARNING
ELECTRICAL SHOCK HAZARD! For your safety, to avoid the risk of electric shock, disconnect electrical power to the
device before servicing or making any electrical connections. DO NOT re-connect electrical power until ALL wiring is
completed. Failure to do so may result in severe personal injury or death.
Use a separate circuit breaker for the Genesis Heat-Timer
equipment, pumps, or motors. Heat-Timer recommends the installation of a surge suppressor and a power switch before
the power line connection.
Follow all local and state electrical codes when installing this unit. All wiring must meet or exceed local, state, or federal
codes and requirements.
1
De-energize the circuit that will provide power to the Genesis Heat-Timer
turning off the appropriate circuit breaker.
2
Run the 120Vac power wiring through one of the knockouts located on the bottom of
the Genesis Heat-Timer
®
CAUTION
The input power wires must be N.E.C. Class 1. Class 1 voltage wiring must use a
different enclosure knockout and conduit than any sensor wiring.
3
Connect the Hot line to terminal 1 on the Genesis Heat-Timer
4
Connect the Neutral line to terminal 2 on the Genesis Heat-Timer
5
Connect terminal 3 on the Genesis Heat-Timer
Neutral line as the earth ground.
WIRING AUX INPUT TERMINALS
(TERMINALS 20, 21 AND 22, 23 AND 24, 25)
The AUX input terminals will accept a temperature sensor or switch closure. The AUX input must
be configured on ICMS.
Each Aux terminal can connect to only one temperature sensor or one switch closure. When wiring
a temperature sensor, use Heat Timer temperature sensor P/N 904220–00 for measuring system
temperatures or Heat-Timer Wired Room Sensor P/N 904001–00 for measuring space temperature.
