OPTIONAL FEATURES Continued

CIRCULATOR ACTIVATION OPTIONS

When in the default mode, the HydroStat activates the circulator (C1/C2 contacts) on calls to T/TV. The control can be pro-

grammed to activate the circulator on calls to I1/I2 in place of, or in addition to, calls to T/TV.

To change how the Circulator is activated

1. Turn the LO TEMP dial to access the Program Mode – indicated in the display as Pro

2. Turn the HI TEMP dial to select feature 4

3. Push the Test/Settings Button to select between the following options:

- Circulator on T/TV call only

- Circulator on I1/I2 call only

- Circulator on both T/TV & I1/I2 calls

4. Reset LO TEMP and HI TEMP settings to desired temperatures (see page 11

CIRCULATOR HOLD OFF (ENHANCED CONDENSING PROTECTION)

To reduce the potential for condensing, on a call for heat the control will allow the boiler to heat to 125°F prior to energizing the

circulator. Once energized, the circulator will remain on for the duration of the heating call unless the boiler temperature drops

below 115°F. If this occurs, the circulator will re-energize when the boiler returns to 125°F.

To activate Circulator Hold Off

Outdoor Reset and Warm Weather Shutdown

Attach the spade connectors to the right and center posts (OR and C) for full outdoor reset functionality including warm weather

shutdown protection. Wiring this way overides the Thermal Targeting function of the Fuel Smart HydroStat control. (See pg.11)

Warm Weather Shutdown Only

only. When wired this way, the Fuel Smart HydroSTat control will utilize its internal Thermal Targeting function to reset the boiler
