This schedule is defined with the following Economy and Comfort
periods:
• Comfort: 6:00a to 8:00a and 5:00p to 10:00p.
• Economy: 8:00a to 5:00p and 10:00p to 6:00a.
The SunTouch 500650 controls the heating system according to the
setpoints defined in the four programs.

programming mode.
• It is faster to program the same schedule for the entire week; then
modify the exception days.
• See Temperature Setpoint for more information on how to modify the
Comfort and Economy setpoints.
• You can program up to 4 different settings for each day of the week.
Prior to making changes, use this blank template to record your

REMOTE INPUT
The FloorStat is equipped with a remote input which allows connection
of a telephone controller or any other remote control system. When a
signal is received through this input, the FloorStat will automatically
switch fr
om normal operating mode to Vacation mode ( ), or vice
versa. Y
ou can, for example, heat your countr
y house from your office on
Friday
, or your house fr
om the airpor
t, or fr
om your car on your way back
from vacation.
CHARACTERISTICS
This FloorStat works differently than
a conventional electromechanical type.
The latter can have a differential of
temperatur
e up to 7.2°F (4°C) while this
electronic FloorStat has one of only
0.9
°
F (0.5
°
C). This slight oscillation
eliminates the discomfort often found with
conventional electromechanical thermo-
stats. The pr
opor
tional contr
oller deter-
mines the amount of power required by
the floor heating system to maintain the
desired temperature setting.
To see this process, the display shows, in real time, the percentage of
power applied to the electric heating system.
Percentage (100% = 1 cycle)
CYCLES 20% 40% 60% 80% 100%
15 min. 3 min. 6 min. 9 min. 12 min. 15 min.
Example for FloorStat with 15-minute cycles:
For example, when the screen displays (which equals 40% or 6 min-
utes), then the heating system will be ON for 6 minutes, then OFF for
the remaining 9 minutes of the 15-minute cycle. The heating indicators
refresh when a new cycle starts.

MEMORY BACKUP
In the event of a power failure, an internal circuit will maintain the pro-
gramming. Only the time will have to be set if the power failure is more
than two (2) hours. The FloorStat will return to the same operating mode
as set before the power failure.
