range for any of the zones, power to the heated

automatically goes OFF and the system resets when
the temperature is back in range.
Resetting the Supply Unit After the Inactivity T imer
(Worklife Timer) Has Been Triggered
Your system may have an inactivity timer. If the pump
has not moved for a set amount of time, the inactivity
timer:
D
turns off power to the heaters
D
lights the AUTO HEAT OFF light
For information about setting the time period on the
inactivity timer, see the documentation that came
inside the control panel.

1. Turn the HEAT switch (66) to the OFF position,
then turn it to the ON position.
2. Wait until all components in the supply unit have
returned to operating temperature.
3. Resume operation.
Resetting the Ground Fault Interrupt
This control panel is equipped with a ground fault
interrupt (GFI) circuit breaker (Fig. 6). If the disconnect
switch is ON, but all lights on the electrical control
panel are off, have a qualified electrician check the
ground fault interrupt.
WARNING
ELECTROCUTION HAZARD
To reduce risk of injury or damage to
equipment, perform this procedure with
the main disconnect OFF.
To reset the ground fault interrupt, have a qualified
electrician:
1. Turn OFF the electrical disconnect on the electrical
control panel.
2. Open the electrical control box and locate the
Ground Fault Interrupt switch (71). The GFI should
be in a “neutral” position, between the ON and
OFF positions.
3. Move the GFI switch to the OFF position, then
move it to the ON position.
4. Close the door and turn ON the disconnect switch.
For more information about the GFI switch, see the
documentation that came with the electrical control
panel.
