Thermostat Controls and Display

The following figure shows the thermostat controls. The thermostat has

three temperature control modes:

• AFmode:(Defaultmode)Controlsthesystembasedontheambi-

ent air temperature and ensures that the floor temperature does not

exceedthedesiredlimitsusinganexternalfloortemperaturesensor

• Fmode:Controlsthefloortemperatureusinganexternalfloor

• Amode:Controlsthesystembasedontheambientairtemperature

Place the switch in Standby to cut power to the heater when not in use

(e.g., in the summer). This will not affect the time and temperature

settings.

To reset the ground-fault protection, switch the thermostat to Standby

andbacktoOn.

The thermostat displays the percentage of heating time required to

maintainthedesiredtemperature.Forexample,

is displayed when

heating is activated 40 percent of the time.

Ground-Fault Protection

TheQuickStat-TChasabuilt-inGFCI(5mAtriplevel).Thisprotects

users against risks of electrocution by cutting off the power to the

floorheatingsystemwhentheleakagecurrentexceeds5mA.Ifa

ground-fault has occurred, the TEST light on the top of the

thermostatwillilluminateredandGFIwillappearonthescreen.

Testing the GFCI

UsersshouldtesttheGFCIaftertheinstallationoftheQuickNetfloor

heating system is complete to ensure that the ground-fault protection is

inworkingorder.UsersshouldtesttheGFCIonamonthlybasis

thereafter.

1.TheGFCIcanonlybetestedifthethermostathasaheating

demand.Increasethesetpointtemperatureabovethecurrent

measured temperature. Wait several seconds to allow the

thermostat to adjust to the new set point and the heating symbol

appears.

2.PresstheTEST button.

The test is successful if the TEST light on top of the thermostat

illuminatesredandGFIappearsonthescreen.

The test has failed if the TEST light on top of the thermostat does not

illuminatered.Inthiscase,turnthepowerofftothefloorheating

system and check the installation of the thermostat.

Resetting the GFCI

IftheGFCIhastripped,resetitbyswitchingthethermostattoStandby

and back to On. The TEST light on top of the thermostat will go off.

IftheGFCItripsinnormaloperationwithoutpressingtheTEST button,

there could be a ground-fault. To check whether it is a ground-fault

ornuisancetripping,resettheGFCI.IftheGFCIdoesnottripafterthe

reset, it was nuisance tripping and the system is functioning properly.

IftheGFCItripsagainafterthereset,thereisaground-fault.Theuser

should contact a qualified electrician to troubleshoot the issue.
