for fan continuous operation or is dependant upon connection
to the fan supply input . When internally wired for fan
continuous operation, the fan will be off when the system
switch is off. When dependant upon external connections the
fan may not be off with the system switch in the off position.
The fan supply input is switched to fan speed outputs (HI -
MED - LO).
SWITCHED POWER: L1 power is switched to this output any
time the system switch is out of the OFF position.

Application Notes
To use a remote sensor, remove jumper JP-1 to disable

local sensing. See

using a remote sensor will cause improper operation of
the thermostat. Some units do not have remote sensing
capability.

Units with remote sensing capability have a four-position
terminal block at TB1. If TB1 is two position the unit is
local sensing only.
Remote probe wiring should be located away from any
3
electrical motors or power wiring
Some units are internally wired for permanent fan
4
continuous operation.
On units with a Fan Supply input, the operation of the
5
fan is determined by wiring connection. For fan
continuous, jumper the Fan Supply input (TB2-5) to the
Switched Power output (TB3-3).
For fan cycling operation with a call for heat or cool, a
6
fan relay must be used.
