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

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

T/TV call only

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

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.

OUTDOOR RESET READY AND WARM WEATHER SHUTDOWN
Hydrostat Control model 3200 - PLUS features outdoor reset ready (must use optional kit part no. 430423000)
See installation instructions packed with the kit.
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.12)
Warm Weather Shutdown Only
Connect the wire ends to the left and center spade connectors (WWSD and C) to add Warm Weather Shutdown functionality
only. When wired this way, the Fuel Smart HydroSTat control will utilize its internal Thermal Targeting function to reset the boiler
temperature. (See pg.10)
