OPERATING (CONTROLS)

Dual Temperature Control System
For convenience and economy all MiniMax Commer-
cial heaters are equipped with two thermostats on the
front of the heater control panel; see Figure 3.
Figure 3.
The Pool/Off/Spa switch allows the heater to be turned
off when heating is not desired.
1. "Pool" position - Maintains selected pool
temperature.
2. "Off" position - Heater will not come on
regardless of drop in pool or spa temperature.
3. "Spa" position - This allows separate control of
spa water temperature.
INDICATOR LIGHT DESCRIPTION
The MiniMax Pool Heater provides six status indicator lights, seen from the front of the control panel,
which help you understand the operation of the heater. If something should go wrong, the lights will aid in
troubleshooting the problem - additionally three lights can be seen after opening the control panel. These
three lights give the service technician advance troubleshooting capability. All the LED lights are green with
the exception of the red service LED.
POWER LIGHT (POWER)
The light is on at all times, in any switch position,
indicating 24 VAC power is being supplied to the
control circuit. If it fails to light, no other light will
be on. Possible causes are: a) external power to the
heater is disconnected, check service panel circuit
breaker or fuses; b) local circuit breaker inside the
heater, at the junction box, has tripped -- investigate
cause before resetting; c) transformer has failed.

TO TURN OFF GAS TO HEATER

4. Push in gas control knob slightly and turn clock-
wise to "OFF". Do not force.
5. Replace control access door.
SELECTOR DIALS
The selector dials eliminate constant thermostat
adjustments. Set the spa dial at the desired spa
temperature and the pool dial at the desired pool
temperature. This provides convenient preset
operating temperatures.
THERMOSTAT KNOB STOPPER
Each thermostat is equipped with a mechanical stop
that can be locked or unlocked with use of a
screwdriver to prevent temperatures in excess of
that desired by the user; see Figure 4.
The maximum setting can be adjusted by loosening the
screw "A" and turning the stopper dial to desired
maximum setting. Lock the setting by tightening the
screw.
THERMOSTAT (TSTAT)
This light is on when the thermostat contacts close,
signaled by the water temperature falling below the
setpoint, calling for the heater to fire to maintain the
desired water temperature.
