AFFINITY DUAL CAPACITY HYDRONIC INSTALLATION MANUAL
HydroZone Controller Instructions cont.
All these temperature settings are with increments of 1°F. The dead band is 2°F to 15°F with increments of 1°F.
Tank Temperature Set point is calculated internally by the outdoor reset algorithm, and updated every 30 minutes if
this setup is selected.
Warm Weather Shutdown:
If the warm weather shutdown is selected, the controller will check the
outdoor air temperature sensor every 30 minutes. If the temperature is
higher than the set temperature selected for 50 continuous hours, then the
HydroZone Controller will enter the warm weather shutdown mode. If the
temperature drops below the selected setpoint for 5 continuous hours, the
controller will exit the warm weather shutdown mode and return back to
normal. Warm weather shutdown selections are None, 45, 50, 55, 60, and 65.
The factory default is None.
2.
Tank Control Auto - This function will put the heat pump in cooling or heating
to control to a
single
tank setpoint (default is 120°F). This feature is
not
an
auto-changeover control of the conditioned space. If both heating and cooling
are desired in the
conditioned space
, then heating and cooling will need to
be selected manually with their own tank setpoints in the Tank Control Manual
screen. Default temperature for tank setpoint is 120°F with a 5°F deadband.
The set range is 40°F to 130°F (up to 150°F on NHW), with increments of
1°F. The dead band is 2°F to 5°F with increments of 1°F. The setpoint can be
changed from the main screen by pushing the UP or DOWN buttons.
Selecting ENTER shall take the screen to the CONTROLLER SETUP screen.
This option will maintain the temperature with a tighter deadband and
automatically switch the heat pump between heating and cooling to maintain
a single setpoint. The factory default is 120°F heating and 5°F dead band.
3.
Tank Control Manual - There shall be no automatic changeover from
heating to cooling or vice versa. Heating and cooling modes must be
selected manually.
If heating fixed is selected, the default temperature for tank setpoint is 120°F
with a 10°F deadband. The set range is 80°F to 130°F (up to 150°F on NHW),
with increments of 1°F. The dead band is 2°F to 15°F with increments of 1°F.
The factory defaults are 120°F heating and 5°F dead band, 80°F cooling and
5°F dead band, and warm weather shutdown is None. When the selection is
