Notes<br />
1 - Disconnect for 15 degree source side freeze detection setpoint.<br />
2 - Disconnect for 15 degree load side freeze detection setpoint.<br />
3 - Acc output is cycled with the lead compressor.<br />
4 - If no flow proving switch is being used on the load side, the input must be jumpered<br />
to PB2 - 2 for the unit to operate.<br />
5 - If using a source side flow proving switch, hook up as shown. If no flow proving<br />
switch is being used on the source side, the input must be jumpered to R for the<br />
unit to operate.<br />
6 - Jumpers must be set as shown for correct control operation. If a communication<br />
card is present, it must be removed to check the jumpers.<br />
7 - Reversing Valve will be energized for heating mode.<br />
8 - Used for Emergency Shutdown in conjunction with a normally open relay.<br />
9 - M1 and M2 are located on the compressor protection modules (CPM1 and CPM2)<br />
inside of the compressor junction Boxes. Only used on 360 and 540 models.<br />
