enable and disable a pump with full time power).
The control will also power one of the Variable
Pump outputs to select the pump speed. Pin 5 will
enable Speed 1, Pin 4 Speed 2 , Pin 3 Speed 3
and Pin 2 Speed 4.
• Variable - The control will close and open the
Pump Relay to turn the pump on and off (or to
enable and disable a pump with full time power).
Variable Pump output Pin 2 will provide a signal to
directly control the speed of a pulse width modula-
tion ('PWM') pump motor.
Spa Heat Speed (Selection available only with
Pump Operation enabled and 2, 4 or Variable
speed pump)
Use the UP and DOWN buttons to select between the
available options. Available options will be based on
the Pump Operation selected in the previous step.
Spa Heat Speed must be set to provide a minimum of
40 gpm to the heater.
Pool Heat Speed (Selection available only with
Pump Operation enabled and 2, 4 or Variable
speed pump)
Use the UP and DOWN buttons to select between the
available options. Available options will be based on
the Pump Operation previously selected. Pool Heat
Speed must be set to provide a minimum of 40 gpm to
the heater.
Filter Speed (Selection available only with Pump
Operation enabled and 2, 4 or Variable speed)
Use the UP and DOWN buttons to select between the
available options. Available options will be based on
the Pump Operation previously selected. Filter speed
should be set to provide the required turns for proper
sanitation, calculated based on the estimated Filter
Speed flow rate, body of water volume and the sched-
uled pump on time.
Freeze Protect (Selection available only with Pump
Operation enabled)
Use the UP and DOWN buttons to enable or disable
freeze protection. When Freeze Protect is enabled the
control will monitor water temperature when in Remote
and Run Schedule modes. If the water temperature
sensor on the heater measures a temperature below
40ºF (4.4ºC) the control will activate the pump for 15
minutes. After 15 minutes the pump will shut off once
the water temperature exceeds 42ºF (5.5ºC).
Valve Operation (Selection available only with
Pump Operation enabled)
Use the UP and DOWN buttons to enable or disable
operation of motorized three-way valves.
Return Valve (Selection available only with Valve
Operation enabled)
Use the UP and DOWN buttons to define the valve
positions for the Return Valve. Valve Position 1 can be
set to Pool or Spa.
Suction Valve (Selection available only with Valve
Operation enabled)
Use the UP and DOWN buttons to define the valve
positions for the Suction Valve. Valve Position 1 can
be set to Pool or Spa.
Valve Chng Delay (Selection available only with
Valve Operation enabled)
Use the UP and DOWN buttons to enable or disable
the Valve Change Delay function. When enabled, the
pump will be turned off for 30 seconds before the
valves will begin to change positions. After 30 sec-
onds for the valves to rotate (1 minute total off time)
the pump will be re-started. If the water flow switch is
closed (indicating water flow is present) when the con-
trol is attempting to change valve positions, "WPS
Closed" will be indicated on the LCD, and the control
will wait for the water flow switch to open before
resuming operation.
Aux 1
Use the UP and DOWN buttons to select between
OFF, Ext Heat, Remote Out and Aux Output.
• OFF – The Aux 1 relay is not used.
• Ext Heat – The Aux 1 Relay activates an external
heat source when the thermostat has a call for
heat. The external heat source operates as the
first stage of heating with the master heater acting
as the second stage, activating the second stage
when the water temperature is 2ºF (1.1ºC) or more
below setpoint.
• Remote Out - The Aux 1 relay will provide a par-
allel output to a remote device such as an external
heat source when the thermostat has a call for
heat. The master heater will operate according to
thermostat demand with the Aux 1 relay closing 10
seconds after the master heater has started heat-
ing. The Aux 1 remote output will cease when the
heat demand is satisfied.
• Aux Output - The Aux 1 relay will close and open
according to the Run Schedule program or Manual
Override commands.
Aux 2
Aux 2 provides a second relay output with the same
options as Aux 1. Note that with 2-speed pumps Aux
2 will not be available as it is used to enable high pump
speed.
