3.3.8 Operating mode switch
The operating mode switch for the controller and heat pump are set to the "OFF"-
position after the system diagram has been loaded. In this position, no temperature
setpoints are calculated and no control outputs activated. To place the system into
automatic operation, the operating mode switches for the controller and the heat pump
must be set to "AUTO". The switches can be located by pressing "+" while in the
default display. Select the required operating mode switch using "DOWN". Use "+"
or "-" to set the switch to the desired position and press "OK".
3.3.9 Testing the functionality
Testing the connected sensors and the correct functionality of the outputs is an
important step during initial installation.
Sensors
The value measured at each connected sensor can be seen in the menu "Current
value" in each module. If a sensor is missing, or if its cable has broken or suffered a
short, it will be shown in the default display (e.g. as the error message: "TI-input,
trouble indication Term: xx"). The "status" menu of each module will detail which
error was recognized on which sensor (e.g.: outdoor sensor too high – cable broken,
oudoor sensor too low – short in cable or in the sensor).
What to do:
Outputs
To check the functionality of the connected valves and pumps, the following steps
must be followed:
Solve any eventual wiring problems.
Measure the signal/resistance of the disconnected sensor. If nesseccary,
replace the sensor. A table of sensor measuring vaues is contained in the
appendix of this manual.
Sensors which have been assigned by loading the system diagram, but which
are not needed or not connected, must be deleted in the menu "System –
terminal assignment" in the associated module.
1.
Set the operating mode switch to "manual".
2.
The menu "manual" of each module permits manual control of the connected
component. Parameter value "3" sets the pumps and the the 3-point actuators
to "automatic". "101" will do the same for actuators with continuous control
(0...10 V).
3.
Changing the parameter to "0" will cause the HPM controller to issue a
"CLOSE" signal to 3-point actuators, an "OFF" signal to pumps and a 0%
control signal to actuators with continuous (0...10 V) control.
4.
Changing the parameter to "1" will cause the HPM controller to issue an
"OPEN" signal to 3-point actuators and an "ON" signal to 2-point-controlled
components. Entering a value between 0...10 enables testing of the complete
continuous control signal (0...10 V).
5.
After all testing has been performed, all values must be reset to their original
state and the operating mode switch set back to "AUTO".
