Notes
2 - Disconnect for 15 degree load side freeze protection 3 – Acc output is cycled with the lead compressor. 4 - A field installed flow switch is required for the load side and must be connected to PB2-3 for the unit to operate. 1 - Disconnect for 15 degree source side freeze protection 6 - Jumpers must be set as shown for correct control operation. If a communication card is present, it must
be removed to check the jumpers.
5 – A field installed flow switch is required for the source side and must be connected to R for the unit to operate. 7 – Reversing Valve will be energized for heating mode. 9 – M1 and M2 are located on the compressor protection modules (CPM1 and CPM2) inside of the compressor junction boxes. Only used on the 600 model. 8 – In Emergency Shutdown, line voltage is still present in control box. Emergency Switch is wired on low voltage circuit only.
