16 - UNIVERSAL INPUTS
The V300 controller is equipped with two configurable potential free inputs. These two inputs, D1
┴
and D2-
┴
, are supplied from
the factory with a bridge. If you want to connect contacts to the inputs (frame contact for example), the bridges must be removed.
. Universal input D1
This input can be configured using parameters P14 and P16
P14: Action direction of contact, NO or NC
P16: Enables the user to slave controller operation to contact opening or closure, with the possible set-up below:
0: Inactive
1: Frost protection
2: Economy
3: Alarm
4: LS* air purification
5: MS* air purification
6: Off
. Universal input D2
This input can be configured using parameters P15 and P17
P15: Action direction of contact, NO or NC
P17: Enables the user to slave controller operation to contact opening or closure, with the possible set-up below:
0: Inactive
1: Frost protection
2: Economy
3: Alarm
4: LS* air purification
5: MS* air purification
6: Off
. Note D1 and D2:
- Make sure that the two D1 and D2 inputs are always configured differently (to avoid the risk of conflict between identical values
on two separate inputs).
*Note:
- Warning: LS or MS Purification function not compatible with "Air" control (without valves)
The control parameters (proportional band, integral time) are preset in the factory. Precise values have been validated in the
laboratory and enable "Comfort" operation in most comfort unit applications. Modifications to these remain the user's responsibility.
Deadband ventilation
In the comfort operating mode, the deadband ventilation is set in the factory as follows:
. Comfort mode (P19): 0 Fan stoppage (if controller with room sensor) or 1: periodic restarts (if controller with return sensor).
It is possible either to cut off the ventilation after 2 mins of post-ventilation (P19 = 0), or have constant low speed ventilation (P19
= 3), or have constant ventilation in the summer and for it to cut out in the winter (P19 = 5), i.e. ventilation on every 30 mins for 1
minute (P19 = 2).
If control is applied using the return sensor, it is strongly recommended to have continuous low speed ventilation.
The setting of these parameters is derived from a compromise between control precision, physiological comfort and energy
saving (see details of P19 in the parameters table).
Note: For air control (without valves), make sure that P19 is set to 0 to avoid problems with overheating or cooling caused by the
ventilation.
Minimum ventilation time
In automatic ventilation, the controller automatically engages the ventilation speeds. To limit the number of ventilation speed
changes, there is a stipulated minimum ventilation run time of 2 minutes at each speed.
Comfort override delay
To control energy consumption, the controller may limit the operating time in comfort mode following a user override. Parameter
P54 enables you to set a timer between 1 hr and 12 hrs, or to prohibit any comfort override (P54 = 0). This function can be
disabled (P54 = 13). It is generally used with a zone timer (see corresponding instructions)
Operating mode activated by standby key
Depending on parameter P08, the sleep button can be pressed to switch between the controller's 4 operating modes: Comfort,
Economy, Frost protection and Off.
2-pipe + radiator application or 2-pipe + electric convector application
The control enables one radiator equipped with a 230V thermostatic valve or an electric convector (230V/2000W max) to be
actuated via P21 = 2
In this case, during the heating sequence, the V300 control stops ventilation
of the comfort unit and triggers the connected electric convector or radiator valve in on/off mode.
The electric convector must then be wired directly to the V300 control
via the dedicated output for the electric coil (230V/2000W max) / the 230V thermostatic valve can be actuated either by this same
output or by the free valve output (P25=1)
