4.6 ADJUSTING THE MIXING VALVE
A thermostatically controlled mixing valve works automatically thanks to the thermostatic element controlling the mix of very hot and cold water as required to provide safe domestic hot water under variable conditions.
To adjust the mixing valve setting, carefully open a hot water tap. Protect yourself against the possibility of scalding. Measure the hot water temperature and adjust it with the mixing valve, following the manufacturer’s instructions. Lock the adjusting valve in place at the proper setting.
A higher boiler water temperature setting is now possible thanks to this moderating effect. The boiler water in the COMBOMAXMC tank acts as a buffer and increases the boiler efficiency as well as the amount of domestic hot water produced.
To increase the ad hoc or general hot water production capacity, first adjust the domestic hot water priority aquastat setting (e.g., from 140°F to 180°F), then the mixing valve setting (e.g., from 90°F to 120°F).
Some sanitary uses may require different setting ranges or dedicated piping.
