Installing Universal 10K Ohm Sensor Kit
HYDROMAX models with a mechanical aquastat
include a universal temperature sensor kit allowing
HYDROMAX to be used with any boiler control featuring
a standard “10K” DHW thermisor input (10,000 Ohms at
77° F). When installed, domestic water temperature is
regulated by the boiler and the HYDROMAX aquastat is
not used.
1. Unscrew and remove copper sensor bulb from
sensor well.
2. Insert Universal Sensor to bottom of sensor well.
3. Plug Universal Sensor into Extension cable.
4. Connect wire leads to DHW input terminals on
boiler control.
