FAQs, GENERAL INFORMATION & OPERATING TIPS
Frequently Asked Questions (FAQs)
What about my thermostat operation?
Your unit is controlled by one or more thermostats. Thermostats sense the temperature in the room in which
they are located and determine the mode of the unit (heating or cooling) and control the duration of the cycle.
WaterFurnace offers a variety of thermostats, each one operates on the same principle but their settings, buttons
and commands are different.
For more information on the thermostats offered by WaterFurnace, refer to pages 19-27.
What do I do in case of a power failure?
Don’t worry. Today’s electronic thermostats employ the latest developments in solid-state technology. Most elec-
tronic thermostats do not require a battery in order to maintain your selected set points in the event of a power loss.
The thermostat memory is unaffected by power failures of any duration. When power is restored, the thermostat will
continue operating as if the power had never been interrupted. However, there will be no heating or cooling during
the outage.
What if my unit stops working?
Your unit has been equipped with a variety of self-protection devices and controls. Should you suspect that heating
or cooling operation has ceased, look at the thermostat to see if the unit lockout indicator light is illuminated. If the
lockout indicator light is illuminated, see resetting the unit section, page 33.
What about regular service?
Your system requires little regular maintenance. However, once a year or so, have the unit inspected by your dealer.
They will check the unit’s performance and make sure that your unit is heating and cooling at its peak performance
level. If your system is using a well as its water supply, your unit may need periodic cleaning to remove
mineral deposits.
What kind of safety controls does my unit have?
Your WaterFurnace unit is equipped with safety controls which are
designed to protect the unit in case of improper airfl ow, water fl ow or
refrigerant charge. These safety controls should not be bypassed.
Doing so may void the warranty.
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 re-
quired to correct the situation.
These lights will:
Help determine whether your system is operating correctly.
Help identify any problems.
Help determine if you can fi x the problem yourself and avoid a
service call.
Save you time and expense when you need to call an indepen-
dent WaterFurnace dealer by helping them identify the problem
before they come out.
