5 Coil frost protection When indoor coil temperature becomes 5°F or below,coil frost protection will proceed as follows. After the compressor has been continuously operated for 3 minutes or more,and the indoor coil temperature has been 5°F or below for 3 minutes,the coil frost protection will start. Compressor stops for 6 minutes,and then restarts.

PAGE 47
3. CONTROL USING TWO REMOTE CONTROLLERS Two remote controllers can be used to control either one unit or a group of units. Units operate according to the latest command from either of the two remote controllers. Before operation, be sure to set one remote controller as the “main controller” and the other as the “sub controller”, using dip switch SW17-7 of the remote controller.
PAGE 48
NOTE1 : Install the relay box where you can be serviced it easily. NOTE2 : For control circuit wiring, use a wire of No. 14 AWG or a control cable according to the power supply of control circuit. NOTE3 : When the power supply of the control circuit is 115V AC, ● Do not connect the control circuit wire to the remote controller cable directly. ● Do not place the control circuit wire and the remote controller cable into the same conduit tube.
PAGE 49
6. MULTIPLE REMOTE CONTROL DISPLAY You can control several units with a multiple remote control display, by wiring an optional multiple display adapter (PAC-SA88HA-E) with relays and lamps on the market. How to wire (1) Connect the multiple display adapter to the connector CN51 on the indoor controller board. (2) Wire three of the five wires from the multiple display adapter as shown in the figure below. CN51 X2 YELLOW X1 ORANGE RED Electrical insulation is needed.
