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)
8)
By considering the configuration (proportional; 100 = 100% pos. signal).
(Also applies to damper in FNC20).
T 22
Cooling valve
1) 2) 7) 8)
By considering the configuration (proportional; 100 = 100% pos. signal).
(Also applies to damper in FNC20).
T 23
El. Heating register
3) 7)
Pulse to the electric register (value > 0

10 s pulse).
T 25
Heating surface
1) 4) 7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 27
Damper
1) 4) 7)
By considering the configuration (proportional; 100 = 100% pos. signal).
T 31
Fan relay
RXB2...: Speed control (%-value converted to speeds).
RXB39.1: Speed control (%-value converted to DC 0...10 V signal on YC3)
T 41
Relay Q14
6)
(0 = Relay deenergized; 1 = energized).
T 42
Relay Q24
6)
(0 = Relay deenergized; 1 = energized).
T 43
Relay Q34
6)
(0 = Relay deenergized; 1 = energized).
T 51
Triac Y1
6)
(0 = Triac disabled; 1 = enabled).
T 52
Triac Y1
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.
2)
T21 and T22 have the same effect in changeover applications.
3)
Only for RXB22.1/FC-12 and RXB39.1/FC-13
If a digital input is used by a safety thermostat, the thermostat is considered.
4)
Only for RXB21.1/FC-11 and RXB24.1/CC-02.
6)
If not used by the application.
7)
Only the I/Os of the controller and no bus actuators are controlled in test mode.
8)
For FNC20, the different damper runtimes for heatin/cooling are not considered; for
test mode, the sum of the times are halved
9)
Values are correct when read, but will not automatically be updated.
The positions can be selected with < (Enter).
• The inputs are displayed
• Outputs can be set via < (Enter) and + / –.
To exit test mode, press >- (Escape) 2 - 3 times (depending on the situation).
If no further button is pressed for 5 minutes, the controller automatically reassumes
Normal mode and all physical outputs are switched back.
Monitor and operate
