2 Functional specifications.
To the MC 785D thermostat a maximum of four temperature sensors can be connected. As more
than one sensor is set active the MC785D controls on the average temperature of these sensors.
A maximum for four different setpoints can be programmed.
The MC785D thermostat has standard functions from 1 thermostat with 1 setpoint and 1 relay output
until 4 thermostats with 4 setpoints and 4 relay outputs. Also two-, three- or four-steps thermostat with
one setpoint available.
The MC 785D has the control functions cooling or heating. Also has the controller an alarm relay,
which becomes active as soon as the alarm levels are exceeded, a sensor is broken or the external
alarm input is closed.
The MC 785D has two analog outputs with a range of 0/+10Vdc. The function of these outputs can be
programmed as measuring signal, setpoint signal or a P(I) control for the cooling or heating.
The controller has two digital input contacts. The first contact is used as night offset input, the second
contact as external alarm.
The above mentioned settings are made via the Internal Parameters.
To allow also other combinations between setpoints, sensor and relays, there is the Advanced
Programming. This mode is only advisable for advanced users.

3 Control of the thermostat.
Normally the displays show the measured temperature and the selected setpoint.
Switching the thermostat on and off.
With the ON/OFF key the MC 785D can be switched on and off. Is the thermostat switched off,
all displays are off. No control function is active.
Select and change temperature setpoint.
With the UP and DOWN keys the desired setpoint can be selected. The LED's next to the
setpoint display indicate which setpoint is shown.
By pushing the SETPOINT key, the setpoint starts flashing. With the UP and DOWN keys the
setpoint can be changed. By pressing the SETPOINT key again, the new setpoint is accepted.
Read-out and switching sensors on and off.
By pressing the SENS key the temperature of the first sensor is shown in the upper display.
The lower display shows the number of the sensor and of the sensor is switched on or off.
'S1on' means that the temperature of sensor 1 is shown and that the sensor is switched on.
Sensors that are switched on are used for the control, switched off sensors not. If more sensors
for a thermostat are switched on, the control is based on the average of those sensors.
If during the read-out of a sensor is pressed on the SETP key, a sensor can be switched on or
switched off.
By pressing the SENS key once again, the next sensor is shown. After all sensors are shown,
the average measured temperature and the setpoint are shown in the display.
Reset the alarm.
As soon as an alarm situation occurs and an error message appears on the display can, by
pressing the RESET ALARM key, the alarm be reset.
The error message remains in the display, until the cause of the error is solved.
Day/night input.
If the NIGHT input is closed, the MC 785D turns to the night mode. The NIGHT LED will light.
The setpoints are increased with the night offset.
External alarm input.
If the external alarm input is closed, an alarm message “FE” appears in the display. The alarm
relay is activated. By pressing the RESET ALARM key, the alarm be reset. The error message
remains in the display, until the cause of the error is solved.

4 Programming internal settings.
By pressing the RESET ALARM and SENS key simultaneously for more than 5 seconds, the Internal
Parameter menu is entered. The temperature display shows a P with a number. With the UP and
DOWN key the desired parameter can be selected.
The setpoint display shows the value of the parameter. By pressing the SETPOINT key
simultaneously with the UP or DOWN key, the value can be adjusted.
The parameter table shows the normal programming functions of the thermostat. It is possible to
make other combinations between sensors, setpoints and relays. For these advanced programming
function please see chapter 8 'Advanced Programming'.
If during 30 seconds no key is touched, the display returns to the normal operating mode.

5 Operation relay outputs.
Function selection of the thermostat.
With parameter P 01 the function of the thermostat is selected.
0 (D) = 1-stage thermostat with one setpoint and one relay output.
1 (D21) = 2-stage thermostat with one setpoint and two relay outputs.
2 (D22) = 2 thermostats each with his own setpoint and relay output.
3 (D31) = 3-stage thermostat with one setpoint and two relay outputs.
4 (D33) = 3 thermostats each with his own setpoint and relay output.
5 (D41) = 4-stage thermostat with one setpoint and two relay outputs.
6 (D44) = 4 thermostats each with his own setpoint and relay output.
All these thermostats control on the average temperature off the active sensors.
Operation of the cooling and heating.
For each relay the function cooling or heating can be programmed.
The cooling switches on if the temperature is higher than the setpoint + offset cooling +
differential cooling and switches off if the temperature is below setpoint + offset cooling.
The heating switches on if the temperature is lower than the setpoint + offset heating -
differential heating and switches off if the temperature is above setpoint + offset heating.
Operation of the alarm.
A selection can be made between no alarm, absolute alarm and relative alarm (P 41).
At an absolute alarm an alarm message will follow as soon as one of the active sensor exceeds
the alarm levels. The time delay prevents that an alarm will follow if e.h. the door of the cold
room is opened shortly.
The relative alarm are linked to the setpoint. A relative maximum alarm follows if one of the
active sensors has a temperature which is higher than setpoint + maximum alarm
temperature, taking the time delay into account. A relative minimum alarm follows if one of the
active sensors has a temperature which is lower than setpoint - minimum alarm temperature,
taking the time delay into account.
Display and setpoint.
The range over which the setpoint can be set, can be limited with parameter P 51 and P52.
Also a read-out per 0,1°C or per 1°C can be selected.

MC 785D 0/+100OC Client : General Page : 10 of 20
6 Sensor calibration.
With the parameters P15 to P18 the temperature sensors can be calibrated. Indicates temperature
sensor 1 e.g. 0,2°C too much, the offset (P 15) should be set at -0,2°C.
7 Alarms.
In normal position the alarm relay is on and drops during alarm. This to give an alarm if there is a
power failure. During alarm the alarm LED on the front flashes. Depending on the settings of the
Internal Parameters the control will stop or continue.
An alarm can be caused by:
Temperature alarm : tLO = Minimum alarm temperature
tHI = Maximum alarm temperature
External alarm : FE = External alarm
Sensor failure : F1 = No Temperature sensor on Thermostat-1
F2 = No Temperature sensor on Thermostat-2
F3 = No Temperature sensor on Thermostat-3
F4 = No Temperature sensor on Thermostat-4
E1 = Temperature sensor 1 broken
E2 = Temperature sensor 2 broken
E3 = Temperature sensor 3 broken
E4 = Temperature sensor 4 broken
EA = All control sensors at fault
By pressing the RESET ALARM key, the alarm relay is reset. The error message will remain in the
display until the alarm is solved. Also the alarm LED will remain flashing.

8 Advanced Programming.
By pressing the SETP. and SENS key simultaneously for more than 5 seconds, the Advanced
Parameter menu is entered. The temperature display shows an A with a number. With the UP and
DOWN key the desired parameter can be selected. At first A001 must be set to 1 to make the
Advanced Programming active.
Now all A... parameters can be set. All P... parameters are not active, they can’t be looked at or
changed (Only as A001 =0 the P.. Parameters can be set or shown again).
The setpoint display shows the value of the parameter. By pressing the SETPOINT key
simultaneously with the UP and DOWN key, the value can be adjusted.
If during 30 seconds no key is touched, the display returns to the normal operating mode.
Unless stated else, 0 = NO and 1 = YES.

When Thermostat 1 is used as differential thermostat it controls on the differential
temperature of sensor 1 minus sensor 2.
When Thermostat 2 is used as differential thermostat it controls on the differential
temperature of sensor 3 minus sensor 4.
The sensor has to be assigned accordantly.
