1.1 Intended use
The TempTronic MTC is a programmable room temperature controller for up to
8 TopVent® GV units. It fulls the following functions:
■Regulation of the room temperature with setting option for 3 temperature
setpoints (0…30 °C)
■Clock programme with 10 programmable time blocks
■Summer ventilation (in 3 speeds)
■Destratication mode
■Recording the room temperature with the integrated temperature sensor
■Connection option for external temperature sensor (instead of the integrated
sensor or for averaging)
■Alarm display and reset
■External switching (o󰀨/clock program)
■Keypad lock
■Password protection
Communication is via a 2-wire low-voltage bus system. The TempTronic MTC
cannot be used for 24 V, 230 V or other signals. It may only be used in dry,
dust-free rooms (protection rating IP 30).
Intended use also includes compliance with the operating instructions. Any usage
over and above this use is considered to be not as intended. The manufacturer
can accept no liability for damage resulting from improper use.

3 Programming
3.1 Temperature setpoints
In automatic mode, the controller works with 3 di󰀨erent setpoints for the room
temperature, each of which can be set from 0...30 °C: 'Day', 'Night' and 'Frost'. The
period for their validity can be freely dened in the clock program.
Menu → Settings → Temperatures
Temperatures
Day 21 °C
Night 15 °C
Frost 6 °C
■Set the desired setpoints for automatic
operation according to the clock program.
3.2 Clock program
The clock program is used to dene regular weekly switching times. You can
program up to 10 time blocks. A block looks like this, for example:
Program Block 1
Mo Tu We Th Fr
07:00 Day
17:00 Night
■Days on which the block is valid
■Switching time 1 and temperature setpoint
■Switching time 2 and temperature setpoint
The following options are available for the days of validity:
■Off
■Mo Tu We Th Fr Sa Su
■Mo Tu We Th Fr
■ Sa Su
■Mo
■Tu
(... and so on until Sunday)
Menu → Settings → Clock program
Program Block 1

■Scroll through the programmed blocks
with .
■To edit the selected block, press .
Program Block 1

■Select the validity days with and
press .
■Set '07', '00', 'Day' with and conrm
each time with .
■Set '17', '00', 'Night' with and conrm

3.3 Heating program
In the heating program, you can choose between automatic operation according to
the clock program or continuous operation with a specic temperature setpoint:
■Clock program:
– The controller switches the setpoints as dened in the clock program.
– You can change the temperature manually. The manually changed value
remains valid until the next automatic switching time.
■Continuous day:
– The controller operates continuously with the 'Day' setpoint.
– You can change the temperature manually.
■Continuous night:
– The controller operates continuously with the 'Night' setpoint.
– You can change the temperature manually.
■Continuous frost:
– The controller operates continuously with the 'Frost' setpoint.
– You can change the temperature manually.

■Select the desired heating program.
3.4 Destratification
Destratication mode is used to avoid heat accumulation under the hall ceiling.
When this function is activated, the controller continuously compares the air
temperatures in the ceiling area and in the occupied area. If the temperature
di󰀨erence becomes too great (factory setting 12 K), it switches on the fans of the
connected units and switches o󰀨 the heating until a balanced temperature level is
reached again.
Menu → Settings → DeltaT active

■Activate the destratication mode, if requested.

3.5 Optimisation
You can set the controller so that it starts heating up in automatic mode before the
entered switching time. Heat-up is optimised so that the desired temperature is
reached at the actual switching time.
Notice
■After activating this function, it will take a few days for the controller to
gather the information needed for optimisation.
■The function is programmed so that individual colder or warmer nights
are not immediately included in the calculations.
■Heat-up starts at the earliest 3 hours before the programmed switching
time and not before midnight.
Menu → Settings → Optimiser
Optimiser
→On
Off
■Activate optimisation, if requested.
4 Manual operation
4.1 Overtime program
Use the overtime program if the controller is working in automatic mode and
the current temperature setpoint is to be maintained for a longer period of time
(beyond the programmed switching time).
The overtime timer can be set in 15-minute increments.
Menu → Overtime program
Overtime program
01:15
■Enter the time period. The countdown starts
immediately when you press the key.
4.2 Summer ventilation
The fan can be switched manually to 3 speeds without the heating being in
operation. This can have a cooling e󰀨ect in summer.
Menu → Ventilation

■Select the desired speed.

5 Calibration
The measured value of the integrated temperature sensor may deviate from the
actual temperature under unfavourable circumstances (e.g. due to sunlight or
installation on an outside wall). You can compensate for this temperature di󰀨er-
ence using the calibration function.
Menu → Settings → Calibration
Calibration
Temp. difference
-2.0
■Enter the correction value.
Example:
– The displayed value is 2 °C too high.
– Enter: -2.0
6 External sensor
Optionally, an external room temperature sensor can be connected to the
controller (for connection, see wiring diagram). You can use the measured value of
the external sensor either instead of the integrated sensor or for averaging.
Possible faults of the external sensor are shown on the display (error 3 = no
sensor found).
Menu → Installer → Password → Remote sensor

■If requested, activate the external sensor and
select the desired use.
