Heating mode 

In this mode output is controlled as a typical thermostat, based on Setpoint register and Control 
value (Input value) with differential parameter defined in Differential register. The output signal 
works in 2 states low and high. 
When Control value is lower or equal the difference of Setpoint register and differential register 
the output is in low state. 
When Control value is higher or equal the sum of Setpoint register and differential register the 
output is in high state. 

 

Output in low state: 
Control value >= Se Differential 

 

Output in high state: 
Control value <= Setpoint – Differential 

 

The heating mode algorithm is shown in chart below. 

 

Figure 17 Heating mode algorithm functioning 

 

WARNING!

  In  the  case  when  temperature  sensor  is  failed  (disconnected  or  shortcut)  then 

heating mode does not work and output stays in the false state.
