2.7 Test the periphery using room unit QAX34.3
This function requires a QAX34.3 with index D or higher!
The HandyTool allows you to test the connected field devices (sensors, actuators).
This works only for the controller connected to the HandyTool; master/slave operation
is not possible.
An application must be selected and fully parameterized in the controller (address
and zones can contain default values).
Start parameterization mode:
 Press buttons < , > and – simultaneously for about 2 s until the display turns dark.
 Release the buttons.
 Press button – twice briefly.
 Press buttons + and – simultaneously for approx. 2 s  The display goes dark.
 Press button + twice briefly.
The display now shows
0 (mode 0).
Use + and / or – to choose between the following modes:

0 = Normal mode (normal room unit functions).

1 = Test mode

2 = Display mode (see 2.5.2).

3 = Parameterization mode (see 2.5.2).

4 = Upload (see 2.6).

5 = Download (see 2.6).

6 = Service mode.
The following positions can be selected depending on the type of parameterization.
They are displayed with prefix "T".
The list shows all theoretically possible positions. However, only positions that are
available for selection based on the type of parameterization are displayed.
Theoretically possible positions for periphery testing:
T 01
Sensor input B1
9)
Value of B1 in °C.
T 11
Digital input D1
9)
True state of the contact at D1 (0 = open; 1 = closed).
T 12
Digital input D2
9)
True state of the contact at D2 (0 = open; 1 = closed).
T 21
Heating valve
1) 2) 7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 22
Cooling valve
1) 2) 7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 25
Heating surface
1) 4) 7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 51
Triac Y1
6)
(0 = Triac disabled; 1 = enabled).
T 52
Triac Y2
6)
(0 = Triac disabled; 1 = enabled).
T 53
Triac Y3
6)
(0 = Triac disabled; 1 = enabled).
T 54
Triac Y4
6)
(0 = Triac disabled; 1 = enabled).
1)
Considering the configuration means:
– For thermal actuators, the output is clocked 1:1 during the first 400 s, then as per
the % entry.
– Motorized actuators open at 100% 1.5 times the runtime, and close at 0% 1.5
times the runtime.
