APPLICATION NOTES
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. Units with remote sensing capability have a four position
terminal block at TB1. If TB1 is two position the unit is local
sensing only.
3. Remote probe wiring should be located away from any
electrical motors or power wiring
4. Some units are internally wired for permanent fan
continuous operation.
5. 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).
6. For fan cycling operation with a call for heat or cool, a fan
relay must be used.
7. Observe electrical ratings. Thermostatic outputs are pilot
duty only.
