Synapse SE72 - GFCI Protection and Testing

SYN-INT-E0118
Ground-fault Circuit Interrupter (GFCI)
The GFCI is designed to reduce the risk of electric shock. It
can detect a leakage current of 5mA. If a defect is detected,
the GFCI device lights up, and both screen and heating system
circuit are deactivated. The GFCI can be reinitialized either by
pressing down the Test button or by disconnecting the thermo-
stat at the electrical panel.
Ground-fault Circuit Interrupter (GFCI) Verication
It is important to verify the ground-fault circuit interrupter instal-
lation and operation on a monthly basis.
GFCI verication procedure
1.Increase the temperature set point until the heating power
barsaredisplayed(displayedinthebottom-righthandcorner
ofthescreen).
2.PressdowntheTestbutton.
3.Thefollowingtwocasescanoccur:
a)Successfultest:Theredindicatorofthethermostatlights
up. Inthis case,press down onceagain the Test button
to reinitialize the ground-fault circuit interrupter, the red
indicatorturnsoff.
b)Failed test: The red indicator does not light up and the
entire display blinks during 5 seconds. In this case,
disconnecttheheatingsystemattheelectricalpaneland
callSynapse’scustomerservice.
Lock Option
This mode imposes a maximum temperature set point which
is impossible to exceed regardless of the mode in progress.
However, it is still possible to lower the set point at your discre-
tion. The programming of the Auto and Pre-Prog modes also re-
spects this maximum temperature set point. Please note that
when the lock option is activated, it is impossible to switch from
the Ambient mode to the Floor mode, and conversely.
