The configuration menu Manual operations 3 2
Before refitting the control panel, it may be necessary to alter the switch settings, according to whether the thermostat is used for floor or room sensing alone, or, the most common mode which is both room and floor sensing.
The 2008/2009 model allows you to select floor temperature high adjustment limit 40 C normally, but select 35 C
if floor coverings are unusually temperature sensitive. The temperature display is normally left in C for Australian
The 2010 model provides for room/floor/or room+floor the same, but also allows for a 12 0r 24 hr clock setting.
MODE “R”: Thermostat is used for control by room temperature alone regardless of whether or not the floor
sensor is connected.
MODE “F” Thermostat is used for control by floor temperature alone.
MODE“RF” Thermostat is used primarily for control by room temperature, with floor temperature limits also
capable of controlling the heating. The thermostat is normally supplied pre-set to this position.
The configuration menu
Entering this menu is done by pressing the raise and lower buttons together for about 3 seconds. The display
will show the first item in the menu and pressing SET will move to the next. Your selection is made by using the
raise and lower buttons. (A column is provided for you to plan your settings)
To exit, press the OK button. The program will also exit this mode automatically if no button is pressed for 20
seconds, so it is a good idea to examine your choices first.

Manual operations
Set day and time
Press SET button. The display will show the hour flashing.
Press raise or lower butins to reach the correct hour
Press SET again and minutes will flash. Use raise/lower buttons to adjust
Press SET again and week day will flash. Use raise/lower buttons to adjust
At this point, the installation is complete. The remaining instructions provide for
further operations eg temperature settings for periods of the day, should these be
needed to suit the occupancy of the heated space.
Temporary temperature hold
With thermostat in normal operating mode, use raise /lower buttons to select temperature. The temperature display will
flash. Press OK to hold.
While held in this condition, a “hand” symbol will display. The normal programmed setting will automatically resume when
the time of the next programmed period is reached.
Checking current floor temperature
Hold the raise button for 5 seconds. Floor temperature will be displayed and the symbol to indicate this. Press OK to revert
back to normal operation. This will occur automatically after about 20 seconds.
Reset operation
If the display is abnormal, press the reset gently by opening up a paper clip and using this. All factory defaults will be restored. It will then be necessary to restore the same configuration settings as pre-set by Heatec if these are preferred.
Planning your temperature/time program.
The thermostat is manufactured with a pre-set default program of 7 individual daily programs using 6 temperature changes
per day. (It will revert to this if the above reset process is carried out).
As part of the thermostat testing process, Heatec usually presets a typical time/temperature program as shown in the following table using 4 periods/week day and applying the same times and temperatures to Sat and Sun as well. If this program is not suitable, make the necessary changes. Consider all possible changes before beginning, because if you pause
for more than 15 seconds the thermostat will resume the normal display.
To enter the time/temperature program, press SET for 5 seconds and the week day(s) 1-5 will flash as a group if the suggested option of programming all week days together in the configuration menu has been selected. Press the raise or lower
button to change this to Saturday (6) or Sunday (7) if that is all you wish to alter. Then press SET to commence the temperature/time settings .
A time will then flash at the top of the screen. Raise or lower if necessary, then press SET
The temperature (as selected to commence from this time) will then flash. Raise or lower if necessary, then press SET
Continue the same temperature and time settings for the remainder of the day 4 or 6 periods (according to the configuration
choices set).
The next day will then start flashing. Repeat the day’s time/temperature setting procedure until finished.
When complete, press OK to revert back to normal programmed operation. If you do not press any keys for about 15 seconds it will revert back to normal automatically.
In deciding the commencement time for each period, make allowance for both the warm up and cool down time. This will
depend on installation type. The suggested program below may be suitable for providing a warm up time for a bathroom
where the room is first occupied at 7.00 am and not normally used after 9.00 am. Then often used between the hours of
7.00 pm and 11.00 pm

Heatec SAS818FHL-7 Thermostat for floor heating
Power source: 230VAC
Inbuilt relay capacity: 16A
Floor sensor: 100K NTC Thermistor
Installation is only to be carried out by a licensed electrical worker.
When installed in bathrooms, it must not be located in any restricted zone lower than zone 3 (see AS/NZS3000: 2007).
Unless the thermostat is being used for floor sensing only, it must be mounted where it is exposed to the heated
space, usually at switch height and in a location that avoids direct sunlight or influence from any other heat source. If
used for floor sensing only, it may be located any distance from the heated floor and the floor sensor wiring extended
as necessary.
The thermostat will mount over a standard 70mm x 70mm European square mounting box, or by using a regular Australian horizontal or vertical bracket and cutting out a square hole at one end of the bracket to pick up one mounting
hole and using a plaster anchor for the another.
Any bulk or blanket thermal insulation must be kept clear of the cavity area immediately behind the thermostat.
The control panel is retained against the base by two catches on the top and bottom. Rather than prizing it off with a
screwdriver (which may cause damage) it is better to support the base while applying downward force on the top edge
of the control panel to release the top catches, then withdraw it.

The wiring connections are clearly identified on the base. It will be necessary to wind out the small terminal clamping
screws before inserting the wires. The thermistor connections are not polarity sensitive

will be necessary to reset the time and day.
Error codes
E1 Floor sensor short circuit. (Mode RFor RF) The output will shut down.
E2 Floor sensor open circuited or damaged (Mode F or RF). The output will shut down.
E3 The floor temperature has reached the high limit setting in your configuration menu . (Mode F or RF) The output will
shut down until it drops below the limit. Note: this is a normal function and does not suggest a fault.
E4 The floor temperature is below the low limit set in your configuration menu. Heating will be turned on until this is
E5 The room sensor is faulty (condensation a possible cause) All output will shut down.
E6 The room sensor is faulty. Replacement required. All output will shut down.
