5. If ‘r6’=1 parameters ‘u3’ o ‘u4’ can be programmed; If ‘r6’=2 only parameter ‘u3’ can be
programmed; If ‘r6’=0 we cannot program parameter ‘u3’ or ‘u4’
6. After the last parameter is programmed a led diode on the button is switched off.
E – Alarms and emergency operation
In case of ‘sensor 1’ failure it occurs:
Heating and cooling relays (for block 1) are controlled in time cycle (clock control)
For ‘c8’ time heating relay is switched off and cooling relay is on
For ‘c9’ time heating relay is switched on and cooling relay is off
Switching on all block 1 alarm relays
Alarm code AL1 is displayed
In case of ‘sensor 2’ failure it occurs
Heating and cooling relays (for block 2) are controlled in time cycle (clock control)
For ‘c8’ time heating relay is switched off and cooling relay is on
For ‘c9’ time heating relay is switched on and cooling relay is off
Switching on all block 2 alarm relays
Alarm code AL2 is displayed
If two sensors fail at the same time, alarms AL1 and AL2 are displayed alternately.
The controller can report temperature exceeding alarms.
If ‘temperature 1’ is higher than ‘cooling activation temperature for the block 1’ + ‘d8’ overheating
alarm relay is switched on and the block 1 alarm relay is switched on to.
If ‘temperature 1’ is lower or equal to ‘heating activation temperature for the block 1’ - ‘d8’ overcooling
alarm relay is switched on and the block 1 alarm relay is switched on.
If ‘temperature 2’ is higher than ‘cooling activation temperature for the block 2’ + ‘d8’ overheating
alarm relay is switched on and the block 2 alarm relay is switched on to.
If ‘temperature 2’ is lower or equal to ‘heating activation temperature for the block 2’ - ‘d8’ overcooling
alarm relay is switched on and the block 2 alarm relay is switched on.
Example 1:
Parameters are set: r5=1 i r6=1
entering the programming mode, u1 is displayed and next a value of this parameter
change the u1 parameter value in range of ‘d0’ – ‘d1 - 1’
memorizing u1 value, u2 is displayed and a value of this parameter
