Notice:
The Aquastat controls supplied with
the Trident Boiler are designed only
to maintain water temperature within
the boiler. The actual heating sys-
tem is controlled separately by your
thermostat(s) opening zone valves or
energizing circulation pump(s).
Do not attach a thermostat to the sup-
plied controls.
