required heating load. Comfort mode provides a steady
stream of heated water to the spa, reducing heater on/off
cycles.
Flue Monitor – Flue Temperature Monitoring
Use the UP and Down buttons to select between PVC,
CPVC/PP or OFF for the flue temperature monitor.
Select PVC when using PVC vent materials. For CPVC,
polypropylene or stainless steel vent materials use the
CPVC/PP setting. While it is not recommended, the flue
monitor may be turned off when using stainless steel vent.
The Flue Monitor utilizes a temperature sensor in the
stack and will reduce the firing rate of the heater when the
vent temperature approaches the limits of PVC or CPVC/
polypropylene vent materials.
Max Fan RPM
Use the UP and Down buttons to adjust the maximum fan
speed. Max Fan RPM may be adjusted from 7000-7500
RPM. It may be beneficial to reduce the Max Fan RPM at
high altitude, for installations with long intake air ducting or
to reduce sound levels. Reducing the fan RPM from 7500-
7000 RPM will reduce the maximum input of the heater by
6 to 7%.
Pump Operation – Configure the Pump Control
Use the UP and Down buttons to select between Disabled,
1-Speed, 2-Speed, 4-Speed and Variable pump controls.
Select Disabled if the heater controls will not be used to
control the pump. The filter pump must be operating to
allow the heater to fire.
•
1 Speed – The control will close and open the Pump
Relay activating the pump contactor to turn the pump
on and off. The filter pump must be on before the
heater can fire.
•
2 Speed – The control will close and open the Pump
Relay to turn the pump on and off and trigger Low
speed operation. The Aux 2 Relay will close to enable
High speed.
•
4 Speed - 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).
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 modulation ('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 (151
lpm) 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 (151 lpm)
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 scheduled 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 40°F (4°C)
the control will activate the pump for 15 minutes. After 15
minutes the pump will shut off once the water temperature
exceeds 42°F (6°C).
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 to send the return
water to either the pool or the spa.
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.
