CONNECTING A PUMP START RELAY
When a pump is to be operated by the controller, a compatible relay
must be used. The relay coil will be connected to the master
valve/pump (MV/PUMP)terminal and must be rated for 24 V a.c. at
0.5A
maximum. The relay contacts will be connected to the pump
start terminals and must be rated for use with the particular pump.
Note: Transient suppressors may be needed across the relay contacts
in installations using large pumps.
Caution: To prevent controller damage, do not connect the
master valve output terminal directly to the pump start
terminals.
