FAQ, GENERAL INFORMATION & OPERATING TIPS
Frequently Asked Questions, General Information
and Operating Tips
The following section includes the most frequently asked questions (FAQs) since ownership of a geothermal system is
quite different than ordinary systems. We’ve included operating tips as well as information on how to get the best results
in comfort, savings, and reliability. We want your geothermal ownership experience to be something that you’ll enjoy and
benefit from for many years.
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, and while each one operates on the same principle their settings, buttons and commands
are different. For more information on the thermostats offered by WaterFurnace, visit: waterfurnace.com/thermostats.
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 electronic
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 the section on resetting the unit.
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 that are designed to protect the unit in case of improper
airflow, water flow or refrigerant charge. These safety controls should not be bypassed. Doing so may void the warranty.
