⧫ The ORP and pH relay are directly connected to the input VAC. If you have the PoolWarden set for 220
VAC then the loads must also be 220 VAC.
For 220 VAC operation, the neutral line will be connected to the Red 220 VAC wire and the Line
connection will be to the Black 220 VAC wire. The Neutral connection for pH and ORP relays switches the
Neutral input VAC wire. The relays are double pole double throw and break both lines.
Load / Equipment Connection & Installation
ORP & pH RELAYS: The chemical feed relays for pH and ORP are internally connected to the input VAC
main input which is located on the right side connector on the circuit board through 10 AMP fuses F1 and F2.
No voltage is being supplied to the load / equipment when the relay is off, hence, voltage is being supplied to
the load / equipment when the relay is on. Any standard chemical feed pump or solenoid can be hard wired
directly into the appropriate ORP and pH connection terminals as shown below in PICTURE 4 so long as their
voltage matches the input VAC connected to the PoolWarden.
⧫ VACBLK: Connection to the VAC black (Line) wire
⧫ VACWHT: For 110 VAC connect to the input white neutral wire. For 220 VAC connect to the red VAC wire.
⧫ PH / ORP WHT: For 110 connect to the white neutral wire on the load. For 220 connect to one of the Line
connections.
⧫ PH / ORP BLK: For 110 connect to the black line wire on the load. For 220 connect to the other Line
connection.
⧫ PH / ORP GND: Connect to the green ground wire on the load.
DRY CONTACT RELAYS: A dry contact relay is not connected to any voltage and acts as a switch. To
supply power to a load / equipment (such as a chemical pump) through any of the auxiliary dry contact relays,
the voltage must be supplied using a jumper to the main input voltage. To facilitate this jump, PoolWarden is
equipped with terminals right next to the auxiliary dry contact relay terminals labeled VACBLK, VACWHT and
GROUND. Please note that these VAC terminals are after the 10 AMP fuses F1 and F2.
Relay Board Acronyms for the Auxiliary Dry Contact Relays:
⧫ AUX#NO1: Normally Open aux relay, side 1 of the relay
⧫ AUX#NO2: Normally Open aux relay, side 2 of the relay
