When it comes to HVAC control systems, wiring can feel like a daunting task. However, properly wiring your Honeywell Aquastat can be achieved by following a few simple steps. This article will guide you through the process of wiring your Honeywell Aquastat and provide answers to frequently asked questions.
What is a Honeywell Aquastat?
A Honeywell Aquastat is a controller that is used to regulate temperature in a hydronic heating system. It is designed to maintain a set temperature by turning the burner on and off as needed. The aquastat also monitors the water temperature in the boiler and adjusts the temperature accordingly. The wiring diagram for the Honeywell Aquastat is essential to ensure proper functioning of the heating system.
Wiring Diagram for the Honeywell Aquastat
The Honeywell Aquastat is wired to the boiler through its terminals. The terminals are labeled T and T, T and TV, and ZC and ZR. Terminal T is the line voltage input terminal, while terminal T, T, and TV are used for the thermostat connections. Terminal ZC and ZR are used for the circulator pump and burner control connections, respectively.
| Terminal | Description |
|---|---|
| T | Line voltage input terminal |
| T, T, and TV | Thermostat connections |
| ZC | Circulator pump control connection |
| ZR | Burner control connection |
Here is a step-by-step guide on how to wire your Honeywell Aquastat:
Step 1: Turn off the power supply to the boiler.
Step 2: Remove the cover of the Honeywell Aquastat.
Step 3: Locate the terminals labeled T and T, T, and TV on the Honeywell Aquastat.
Step 4: Connect the line voltage to terminal T and the thermostat wires to terminal T, T, and TV.
Step 5: Locate the terminals labeled ZC and ZR on the Honeywell Aquastat.
Step 6: Connect the circulator pump control wires to terminal ZC and the burner control wires to terminal ZR.
Step 7: Replace the cover of the Honeywell Aquastat.
Step 8: Turn on the power supply to the boiler and test the system.
