WSHP-X Module

Important Wiring Considerations

Please read carefully and apply the following information when wiring

the WSHP-X Module:

1. To operate the WSHP-X Module in Stand-Alone mode, you

must connect power to the 24 VAC input terminal block.

Do not allow wire strands to stick out and touch adjoining

terminals. This could potentially cause a short circuit.

2. The 1 to 5 VDC signals for the Compressor modulation need

to use 18-gauge shielded twisted pair cable, and the Drain wire

must be the GND signal.

3. All 24 VAC wiring must be connected so that all ground

wires remain common. Failure to follow this procedure can

result in damage to the module and connected devices.

4. Be sure all modular wiring harness connectors are seated

ﬁ rmly in their respective modular connectors on the circuit

board.

Installation & Wiring

5. All wiring is to be in accordance with local and

national electrical codes and speciﬁ cations.

6. Check all wiring leads at the terminal block for tightness.

Be sure that wire strands do not stick out and touch adjacent

terminals. Conﬁ rm that all transducers required for your

system are mounted in the appropriate location and wired into

the correct terminals.

Stand-Alone Wiring Single Water

Circuit

To operate the WSHP-X Module as Stand Alone, connect the Module to

a 24 VAC power connection with an appropriate VA rating. See Figure

3 for wiring.
