7. REMOTE CONTROL

The unit may be controlled either by the unit-mount-
ed controls (Control Panel) or by optional Class 2 ther-
mo controller (SC2001 for Cool/Heat Model and
SC2201 for Heat Pump Model) with optional Interface
kit (STK02LVC). Detailed instructions are included in

8. FRONT DESK CONTROL

The unit may be connected to a switch at the front
desk to control on and off operation of the compres-
sor or heater from the front desk with the optional
interface kit. (See the picture below.) When the switch
is set to OPEN, the unit is operable. When the switch
is set to CLOSED, the unit is made inoperative.
Detailed hook-up instructions are in the interface kit.
Follow the recommended wire sizing in the table
below. Two wires must be used from each FDC switch
to each individual unit.

Good wiring practices (e.g. twisted pairs, SEPARA-
TION FROM POWER CIRCUITS) must be followed to
minimize induced voltages which may harm the con-
trol system. Do not use a common line in the FDC
wiring.

A 24V A/C transformer is contained within the unit
and no external voltage should be applied to the unit
through the FDC switch. The Freeze Protection
remains in active mode to help protect against low
temperature damage even though the unit may be
OFF by FDC.
