0. PREFACE
READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THE EQUIPMENT!
This instruction contains all information necessary for an optimal installation, startup and. It can also be used
as a manual for maintenance and service work.
For the function and proper use of this device, all instructions in the assembly and operation instructions must
be followed strictly.
In case of disregarding these instructions, as well as the use of non-original parts, all warranty- and liability
claims are cancelled.
NOTE: This instruction has been made with greatest care. However, this introduction confers no
rights. We reserve the right to change all or part of the contents of this instruction without prior
notice. 1. Short description
The universal thermostat is used as a stand-alone control unit for the components brine defroster / GHX
regulating flap, defroster heater or electric backup duct heater. It has two programmable and independent
switching points (Temp 1 and Temp 2) with adjustable hysteresis.
The control for the electrical consumer is performed by an electronic relay, for electric duct heaters with
modulating power control. Pparallel to this a potential-free changeover is available. Enabling and locking of the
control can be performed by an external potential-free enabling contact. The programmed temperature values
as well as the temperature at the sensor are shown by a 7-segment display. Please see appendix 1: Electrical
connections / Terminal diagram.
2. Function / Operation
2.1 Operating modes
The configuration of the operating mode is done by DIP-switches. After selecting the new operating mode, the
control system has to be restarted (disconnection from supply).
2.1.1 Continuous control for heating elements (Defroster heater / Backup duct heater)
This operation mode is most suitable to achieve a constant air temperature even though the ambient
conditions are changing. The capacity of the heating element is modulated by the control system, so that
the temperature inside the air duct is always constant.
The temperature sensor is installed in the air duct (in air flow direction) downstream of the components
defroster heater / backup duct heater. The control of the brine defroster / GHX regulating flap depends on
the configured temperature threshold X1 (see appendix 1, appendix 3 and appendix 4):
ON: T ≤X1
OFF: T ≥X1+H
DIP-1, -2 ON
DIP-3, -4 OFF
T - Actual value of measured temperature depending on purpose:
- Intake air temperature downstream of defroster heater
- Supply air temperature downstream of backup duct heater
H - Hysteresis
X1 - Setpoint ″temperature switching threshold″
t- Cycle time pulse package control in seconds (s)

2.1.1.1 Settings of operating mode pulse package control
Button “Temp 1“ -> Temperature switching threshold [X1]
- keypress < 3 s = current switching threshold is displayed
- keypress > 3 s = programming mode (display flashes)
- setting range -15°C…50°C, increment: 0,5 K
Button “Temp 2“ -> Time[t] (time interval)
- keypress < 10 s = current unit of time is displayed (sec.)
- keypress > 10 s = programming mode (display flashes)
- setting range 1 - 100 s, increment: 1 s.
Button “Hyst.“ -> Hysteresis [H] to temperature switching threshold
- keypress < 10 s = current hysteresis is displayed
- keypress > 10 s = programming mode (display flashes)
- setting range 0,3…5 K, increment: 0,1 K
2.1.1.2 Setting of temperature switching threshold and switching times
After setting the operation mode using the DIP switches, the temperature thresholds have to be set via the
control buttons. The relevant thresholds can be changed according to the mode of operation.
When the cover is open the set values are displayed by a short keypress of the respective keys for 3 s.
The programming mode can accessed by a long keypress (display flashes) and the setpoint can be changed
by pressing the “+”or “-” buttons. The value, that has been changed using the method above, is saved
automatically if no button is pressed. The display shows the temperature after 3s. The current measured
temperature of sensor NTC1 is now displayed.
Recommended setting values:
Parameter Defroster heater Backup duct heater
X1 -3 20 … 50
H0,5 0,5
t 40 40
Note: The predefined parameters for H and t should only be changed in exceptional cases (bad control
response), e.g. when the temperature can not be stabilized. According to experience, increasing time [t] or
hysteresis [H] can help improving the control response.

2.1.2 ON/OFF Control
In the operation modes mentioned below, the control of the consumer load is realized by switching it
completely on or off.
2.1.2.1 Brine defroster / GHX flap control
The temperature sensor is installed upstream of the components brine defroster or GHX regulating flap.
The control of the brine defroster / GHX regulating flap depends on the configured temperature thresholds
X1 /X2 (see appendix 1 and appendix 2):
ON: T ≤X2 or T ≥X1
OFF: T ≥X2+H and T ≤X1-H
DIP- 1 ON
DIP-2,-3,-4 OFF
T - Actual value of intake air temperature upstream of brine defroster / GHX flap
H - Hysteresis
X1 - Setpoint ″upper switching threshold″
X2 - Setpoint ″lower switching threshold″
2.1.2.2 2-level control for defroster heater
The temperature sensor is installed downstream of the component defroster heater. The control of the
defroster heater depends on the configured temperature threshold X2 (see appendix 1 and appendix 3):
ON: T ≤X2
OFF: T ≥X2+H
DIP-2 ON
DIP-1, -3, -4 OFF
T - Actual value of intake air temperature downstream of the component
H - Hysteresis
X2 - Setpoint ″lower switching threshold″

2.2 Interfaces
2.2.1 External enabling
Terminal X8:
Potential-free input for control enabling. The control is only operational when contact is closed. This input –
in combination with a backup duct heater - can be used for a room thermostat and / or a flow sensor.
2.2.2 Status message “Consumer load ON”
Terminal X7:
Potential-free output for notice „Consumer load ON“. When consumer load is set to active, the relay contact
will be controlled.
(potential-free changeover, switching capacity 230 VAC / 5 A).
3. Error monitoring /-display
Error monitoring is only active for the sensor. If the measured value of the sensor is outside the logical area
(sensor break, -short circuit), “Err“ is shown in the display and the control will be locked. The control will be
ready for operation again after the error has been corrected.

Description:
The universal thermostat is used as a stand-alone control unit for the components brine defroster / GHX regulating flap,
defroster heater or electric backup duct heater. It has two programmable and independent switching points (Temp 1 and
Temp 2) with adjustable hysteresis.
Depending on the application the temperature sensor is used as outside air sensor (for control of brine defroster /
motorised flap GHE), as exhaust air sensor (for frost protection heater) or as inlet air sensor (for after heater). The
relevant mode is set by using a DIP switch.
The control for the electrical consumer is performed by an electronic relay, parallel to this a potential-free changeover is
available. Releasing and inhibiting of the control can be performed by an external enabling contact. The programmed
temperature values as well as the temperature at the sensor are shown by a 7-segment display. The display is visible
through the transparent lid of the existing plastic humidor suitable housing.
