If your controller is configured for Heater Control,
you will have the following options:
Temp. Ctrl Enable (Op): Enables or disables
controlling the Heater using the Temperature
Input.
Set Point (Op): Only shown if Temp. Ctrl is enabled.
This value sets the desired temperature. (the
range is from the temperature low alarm to the
temperature high alarm)
Failsafe Timer (Op): Only shown if Temp. Ctrl is
enabled. This value sets the time that the relay is
allowed to stay on without reaching set point
before the relay is locked out. If the heater has
been trying to achieve set point without success
for the selected time, the controller will cut power
to the heater, flash the Reset Fail/Safe LED on
the face panel and display a message to alert the
operator.
An operator must reset the failsafe through
the Reset Fail/safe button to re-enable normal
control.
Fireman Switch (Op): This option is only shown if a
relay is assigned to the recirculation pump or backwash.
This value sets the minimum amount of time to
leave the recirculation pump on or delay the start
of backwash after the heater relay shuts off.
Hysteresis (Op): Only shown if Temp. Ctrl is
enabled. This value sets the level that the input
must rise above the set point before the heater
control will turn off.
Alternate Temperature (Op): Only shown if Temp.
Ctrl is enabled. The 4 Event 28 Day Timer allows
you to program an alternate set point on a
schedule. See the Chlorine (Bromine) Control's
Alt Set Point for details on how to set this.
After the schedule is set, you may choose the
alternate temperature set point option and enter
the desired setting.
A – 5.8: Chiller
After entering the Control Outputs option, select
Chiller Control from the menu. This will allow the
programming of the following:
Priority Mode (Op): Only shown if the heater relay is

the heater and chiller should operate together.
Mixed Mode: Operates the heater and chiller
like a home thermostat. The chiller's active set
point must be above the heater's or the chiller
will be disabled.
Heater Primary: Operate the heater only
during regular hours and the chiller only during
alternate set point hours. Set the Chiller’s set
point via the alternate set point.

alternate set point hours. Set the Chiller’s set
point via the standard Chiller set point.
Set Point (Op): only shown if no heater or Priority
Mode is set to Mixed Mode or Chiller Primary. This
value sets the desired temperature. (the range is
from the temperature low alarm or heater set point
to the temperature high alarm)
Failsafe Timer (Op): This value sets the time
that the relay is allowed to stay on without
reaching set point before the relay is locked out. If
the chiller has been trying to achieve set point
without success for the selected time, the
controller will cut power to the heater, flash the
Reset Fail/Safe LED on the face panel and display
a message to alert the operator.
An operator must reset the failsafe through
the Reset Fail/safe button to re-enable normal
control.
