Note

1 .Be sure to insert 23CO at the cooling water inlet side.

2.Be sure to wire the 52CH(interlock) between terminals 171 and 136.

З.Ве sure to wire the 52CO(interlock) between terminals 171 and 135.

4.Be sure to wire the chilled water pump control relay between terminals 302 and 303.

5.Be sure to wire the cooling water pump control relay between terminals 304 and 305.

6.Be sure to wire the hot water pump control relay between terminals 345 and 346.
