RatInGs
1. To use a remote sensor, remove jumper JP-1 to disable local sensing.
Failure to remove Jp-1 when using a remote sensor will cause
improper operation of the thermostat. some units do not have
remote sensing capability.
2. Remote probe wiring should be located away from any electrical
motors or power wiring
3. Some units are internally wired for permanent fan continuous
operation.
4. On units with a Fan Supply input the operation of the fan is
determined by wiring connection. For fan continuous, jumper the Fan
Supply input (TB2-5) to the Switched Power output (TB3-3).
5. For fan cycling operation with a call for heat or cool, a fan relay must
be used.
6. Observe electrical ratings. Thermostatic outputs are pilot duty only.
