• Comfor t:
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.

To reset the 500650, press and hold , position switch to
Standby then to On. This will completely erase the schedule and any
modified setpoints.
8. MODIFY THE SCHEDULE
• After 60 seconds of inactivity, the FloorStat will automatically exit
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
Comfor t and Economy setpoints.
• You can program up to 4 dif ferent settings for each day of the week.

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 from normal operating mode to Vacation mode ( ), or vice
versa. You can, for example, heat your countr y house from your of fice on
Friday, or your house from the airpor t, or from your car on your way back
from vacation.
CHARACTERISTICS
This FloorStat works dif ferently than
a conventional electromechanical type.
The latter can have a dif ferential of
temperature 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 discomfor t often found with
conventional electromechanical thermo-
stats. The propor tional controller deter-
mines the amount of power required by
the floor heating system to maintain the
desired temperature setting.

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 star ts.

MEMORY BACKUP
