1.3.3 Reading G(S)+ units and modifying or overruling settings Opti
Connection: maximum 8 G(S)+ units, Op and In
The current status of the devices can be read using Modbus. In addition, the setpoints of the
Op can be changed and the clock program can be overruled. Reset of the units is possible
with the Op. Optionally, the actual room temperature can be determined with a digital
sensor, on the basis of which it is controlled. The Op can then be placed in an additional
room (see for sensor selection the Op manual).
See connection diagram 4.3 for the specific connections for this application.
Explanation of specific Modbus holding registers for this application:
Holding register Access Description Range
201* R + W Heating mode override 0= clock program Op
active
1= off
2= Continuous frost
3= Continuous night
4= Continuous Eco
5= Continuous day
202 R + W Ventilation mode 0 = off
1 = continuous system fan
220 R + W Day Setpoint temperature [°C] (factor 100)
221 R + W Eco Setpoint temperature [°C] (factor 100)
222 R + W Night Setpoint temperature [°C] (factor 100)
223 R + W Frost [°C] (factor 100)
133** R + W CH mode 7 .. 8
* In case after an override (1-5) you want to return to the clock program of the Op,
0 must be written. Modifying this is not possible in the Op menu.
** In this application CH mode must be set to 7 (default setting)
*** Holding registers 122, 204 and 205 do not operate in this application.
1.3.4 Control with contacts (only for GSX units))
Connection: maximum 8 GSX units and In
With an In, one or more GSX units, with a maximum of 8, can be controlled from, for
example, a building management system. All contacts are in this case potential free. The connected
GSX units are controlled simultaneously by means of the following signals: heating, ventilation and/
or reset. When an air heater is malfunctioning or in operation, a notification is given by means of a
potential free contact. The actual status of the units can be read using Modbus.
See connection diagram 4.4 for the specific connections for this application.
