R7426A,B,C  TEMPERATURE CONTROLLER WITH AND WITHOUT REAL TIME CLOCK

Output Signal Mode YMode (C.11) 

Sequence Operation 

The controllers R7426B,C are supplied from the factory 
configured for sequence operation of heating, mixed air, and 
cooling control. 
The sequence operation can be configured for the following 
control applications by the control parameters 

YMode

 and 

Y1CTRF

 (see Table 8). Sequence control will be activated if 

at least one control parameter 

YxMode

 is not equal 4 

(R7426B, only).

Multistage ON/OFF Function 

In the case of the three floating output controller R7426B, 
several ON/OFF sequence control functions can be selected 
by the configuration parameter 

YMode

 (see Table 9).

In the case of the R7426B,C controller, the output Y1 can be 
configured for two-position damper control by setting the 
configuration parameter 

YMode

 to 4. 

 

Supply of Temperature Signal T2 

T2ext (C.12) 

If sensor T1 is used also for high or low limit control, the con-
figuration parameter 

T2ext

 must be set to 1. This inter-

connects the T1 and T2 input internally and the sensor has to 
be connected only to the T1 input. 
By using a limit temperate sensor T2, the parameter 

T2ext 

has to be set to 0 (default). 
 

Limit Type LimTyp (C.13) 

The configuration parameter 

LimTyp

 allows the selection of 

high or low limit control. High limit control is performed if 
configuration parameter 

LimTyp

 = 1; low limit control is 

performed if configuration parameter 

LimTyp

 = 0. 

 

Sensor Type Senstyp (C.14) 

Three different sensor types can be used with the controller 
(see Table 10).

C and the 

configuration parameter Senstyp = 0. NTC sensor is 
selected manually if the configuration parameter Senstyp 
is set to 1. 

 
Automatic identification of sensor type is selected if the 
configuration parameter

 Senstyp

 = 0 (default). After power up 

reset, the controller detects automatically the type of sensor 
connected to the main temperature input T1. For correct auto 
detection, it is necessary that the measured temperature be in 
the specified range (see Table 10). The same type of sensor 
must be used for all temperature inputs (T1, T2 and T3). 
 

Output Control Function Y1CTRF (C.15) 

The R7426A controller performs cooling control if the 
configuration parameter 

Y1CTRF

 is set to 0. A rise in the 

measured variable will increase the output value (direct 
acting). The control action must be reversed for heating 
control by setting the control parameter 

Y1CTRF

 to 1. A rise 

in the measured variable will decrease the output value. 
If the configuration parameter is set to 2, the R7426A 
controller provides summer/winter changeover control by a 
potential-free contact connected to the occupancy input 
(terminals 1 and 4). 
In the case of the R7426B,C controller, the configuration 
parameter 

Y1CTRF

 has to be set to 0 (default) to perform 

mixed air damper control and to 1 for energy recovery 
systems.
