Set Point Parameters Screen:
The Set Point Screen allows access to 6 parameters. Those
parameters are as follows:
• Hot Water Tank Set Point - The hot water tank
set point sets the target temperature of the water in the
tank. This parameter can be changed by the user or the
installer. The temperature range of this parameter is 60°
to 185°F. The default value is 125°F.
• Hot Water Tank On Differential - Sets how many degrees
below the Hot Water Tank Set Point the hot water tank
temperature must drop before the water heater will turn
on. This parameter can only be changed by the installer.
The temperature range for this parameter is 0° to 100°F.
The default value is 5°F.
• Night Setback Set Point - Once the internal clock has
been set correctly, the night setback feature can be used to
program a lower water temperature set point. This
parameter can be changed by the user or the installer.
The temperature range for this parameter is 32° to 140°F.
This feature is turned off with a setting of 32°F. The
default value is 32°F.
• Drop in Inlet Temperature for Ending Anti-cycling - The
control will bypass the anti-cycling time if the inlet water
temperature drops too quickly. The control will use the
inlet water temperature at Heat Exchanger 1 when it shuts
off as the starting point. If the temperature drops below the
temperature parameter the control will abort anti-cycling
and allow the water heater to fire. This parameter can only be
changed by the installer. The temperature range of this
parameter is 0° to 86°F. The default value is 10°F.
• Anti-cycling Time - Once a call for heat has been satisfied, a
set amount of time must elapse before the control will
respond to a new call for heat. The control will block the
new call for heat and Anti-cycling will be shown in the
water heater status display until the time has elapsed or
the inlet water temperature drops below the parameter
drop in inlet temperature for ending anti-cycling. This
parameter can only be changed by the installer. The time
range for this parameter is 0 minutes to 40 minutes. The
default value is 1 minute.
• Hot Water Tank Off Differential - Sets how many degrees
above the Hot Water Tank Set Point the hot water tank
temperature must rise before the water heater will turn
off. This parameter can only be changed by the installer.
The temperature range for this parameter is 0° to 100°F.
The default value is 5°F.
Reference page 17 for information regarding changing
parameters.
