FAQ, GENERAL INFORMATION & OPERATING TIPS
What are the lights for?
Some models are equipped with STATUS lights. These lights are mounted in plain view on the front of your unit. They will
help you properly identify any problems and determine what might be required to correct the situation.
These lights will:
• Help determine whether your system
is operating correctly.
• Help determine if you can fix the problem yourself
and avoid a service call.
• Help identify any problems.
• Save you time and expense when you need to call an
independent WaterFurnace dealer by helping them
identify the problem before they come out.
Why doesn’t my unit have status lights?
While some WaterFurnace units have status lights, others have moved toward communicating thermostats for fault and
error display. Now you can find faults and errors if they occur without checking the actual unit—it’ll be displayed in clear
sight and in plain English on your thermostat.
If my unit shuts off, how do I reset it?
1.
To reset the unit, repeatedly push the SYSTEM button on the thermostat until the display reads OFF.
2.
The unit lockout indicator light will remain on for up to 15 seconds after turning the system off.
3. After the unit lockout indicator light goes out, turn the system back on to the desired MODE.
4. Unit operation should resume within five minutes if heating or cooling is required.
5. The appropriate status light on the unit will continue indicating the fault until power is interrupted to the unit.
This serves as a diagnostic aid for your dealer.
6. If the unit shuts down again, call your WaterFurnace dealer as soon as possible. Do not repeatedly reset your unit.
What if my unit does not operate properly?
Before you call your WaterFurnace dealer for service, check these service hints:
• Check air filters. Depending upon filter type, clean or replace if necessary.
• Make sure the thermostat is set properly.
• Check to make sure the electrical disconnect switches are in the ON position. Both the unit and auxiliary heat
(if present) must be powered for proper operation.
• Check for a tripped circuit breaker or a blown fuse in your home or building’s main power box. Reset breaker
or replace fuse.
• If either the disconnect switch or the circuit breaker continues to trip after you reset it, call your WaterFurnace
dealer immediately to prevent damage to your unit.
• Check the thermostat indicator lights to ensure proper operation of the system.
• Check the unit status lights on the front of the unit to ensure the unit is operating properly.
• If you can’t determine the problem, call your WaterFurnace dealer promptly.
