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 the kit.

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.
