1. Route Thermostat wires.
The thermostat wires are often run through the walls and will emerge from a little hole somewhere in the utility room.
Just below the middle of the control board is a hole to pull the thermostat wires through.
Give yourself enough slack in these wires to not only reach the front of HUG Hydronics tank, but also to move the tank by 12-18”
2. Gently pull out the 12 pin wire connector from the bottom center of the control board.
3. Strip Thermostat Wires
Take a tool and cut about 2 inches of the outer sheath of the thermostat wire. Inside you will see a white and red coated wires (and a third wire for the smart thermostats).
You are going to strip the plastic insulation off each of the thermostat wires.
Insert wire into connector. Mark with your fingers how deep it goes in. Strip the wire to this point.
Use the wire stripper tool provided.
4. For each thermostat: Connect the wires by:
Sticking the white wire in the connector for thermostat zone # it should be connected to. These zone numbers are printed on the control board above the connector.
Tighten the little screw, turn to the right (clockwise) as tight as it will easily go. This should hold the wire securely and make the electrical connection possible.
The red wire will go in one of the power slots (openings in the middle of the connectors) match this to one of the “power” slots on the control board. Tighten as with the white wire. Do not plug the connector back into the control board yet.
Additional Steps for smart Thermostats
- Jumper #JP43 (the one above the “power” section on the control board) needs to be removed to power the smart thermostat. Go ahead and do this now.
Wiring a Smart Thermostat:
The power supply has 2 wires. They will have to be stripped and inserted into the connector. One in to a “power” connector, the other into a “common” connector.
The third smart thermostat wire is also connected to a “common” connector.
Do not plug the connector back into the control board yet.
