The heating relay is switched on when the following conditions are met:
‘temperature 1’ is equal or smaller than the ‘heating activation temperature’.
Cooling relay is switched off.
Block 2 is the same as block 1 but it can be turned off (‘r6’=0).
Analogous to the description of block 1, if 'r6' = 1 (cooling and heating controlled separately):
The adjustment method is shown in figure 1.
‘Heating set temperature’ is set by the user by ‘u3’ parameter, in range of
‘d0’ - ‘d1-1’ (factory setting: u3=2).
‘Heating activation temperature’ is calculated as ‘u3’ – value of heating hysteresis ‘d5’.
‘Heating off temperature’ is calculated as ‘u3’ + value of heating hysteresis grzania ‘d5’.
‘Cooling activation temperature’ is set by the user by ‘u4’ parameter, in range of ‘u3+1’- ‘d1’ (factory setting:
u4=4).
‘Cooling activation temperature’ is calculated as ‘u4’ + value of cooling hysteresis ‘d6’.
‘Cooling off temperature’ is calculated as ‘u4’ - value of cooling hysteresis ‘d6’.
If 'r6' = 2 (cooling and heating control in the same range):
The adjustment method is shown in figure 2.
‘Set temperature’ is set by the user as a ‘u3’ parameter, in range of ‘d0’ - ‘d1-1’ (factory setting: u3=2).
‘Heating activation temperature / cooling off temp.’ is calculated as ‘u3’ – value of hysteresis ‘d5’.
‘Heating off temperature / cooling activation temp.’ is calculated as ‘u3’ + value of hysteresis ‘d5’.
The cooling relay is switched on when the following conditions are met:
'temperature 2' is equal to or greater than the 'heating activation temperature'.
after the time 'c2' has elapsed since the last cooling shutdown.
The heating relay is turned off
after the time 'c2' has elapsed since the power was turned on. *
after the time 'c6' has elapsed - if the 'c5' parameter has been protected - the maximum working time*
*
After turning on the controller with
button, cooling activation time is reduced to:
- 5 seconds, while ‘c2’ is different than zero,
- 0, when ‘c2’ is zero,
It is made to enable service technicians to quickly switch on the cooling.
The heating relay is switched on when the following conditions are met:
‘temperature 2’ is equal or smaller than the ‘heating activation temperature’.
Cooling relay is switched off.
