OPTIONAL FEATURES continued
2-Zone Circulator Settings:
The HydroStat-IC is equipped with a second zone designed for a 120-volt circulator that can be set to operate in one of three
ways:
• Domestic Hot Water (DHW) for use with an indirect water heater
• A Second Heating Zone
• Primary/Secondary Circulator Operation (Important: For use with primary/secondary piping systems only)
See page 7 for details on the operation of each setting as well as the input and output connections for the second circulator. All
controls (except those that are factory equipped on boilers offering primary secondary circulator operation) are factory set in the
Domestic Hot Water (DHW) mode. If, the second zone is going to be used for an additional heating zone, or the boiler is in-
stalled with a primary/secondary piping system, the setting should be changed using the following instruction:
To change the second zone between DHW (priority), Heating (no-priority),
and Primary/Secondary Operation
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 d for DHW, for a second Heating zone, or P for
Primary/Secondary operation.
4. Reset LO TEMP and HI TEMP settings to desired temperatures (see page 4)
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. Circulator Hold Off will expire after 15
minutes. Note: When the control is set for Primary/ Secondary pump operation this feature will default to OFF.
To activate Circulator Hold Off
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 5
3. Push the Test/Settings Button to turn Circulator Hold Off on or OFF
4. Reset LO TEMP and HI TEMP settings to desired temperatures (see page 4)
