6.3.1 Working With Digital Input Configuration As Temperature Control Request
Unit configured as motor-condensing CF04 = 1.
Configure DI as
Cooling/Heating demand digital input (condensing unit).
(DI type = 93)
With DI contact NOT ACTIVE unit in
OFF
With DI contact ACTIVE unit in
cooling/heating
With DI contact active, user can select the cooling or heating working mode by parameter CF02, SP09 and
keyboard. The capacity steps will be called by DI configured as
Capacity step x demand digital input
(x
can be 1 to 16.DI type = 96-111) if resources are available in the circuit.
With DI contact active, user can switch ON/OFF the unit by the keyboard. With DI contact not active, the unit
will always OFF.
6.3.2 Working With Digital Input Configured As Cooling Request
Unit configured as motor-condensing CF04 = 1, CF02=1 or 3.
Configure DI as
Cooling demand digital input (condensing unit)
(DI type= 94)
With DI contact NOT active unit is
OFF
With DI contact active unit is
ON
in chiller mode
With DI contact active, unit works in chiller mode. The capacity steps, if available, will be called by DI
configured as
Capacity step x demand digital input
(x can be 1 to 16)
.
With DI contact active, user can switch ON/OFF the unit by the keyboard. If the unit has been switched-off
from the Visotouch, user can re-start it by deactivate and re-activate the digital input.
6.3.3 Working With Digital Input Configured As Heating Request
Unit configured as motor-condensing CF04 = 1, CF02=2 or 3.
Configure DI as
Heating demand digital input (condensing unit)
(DI type= 95)
With contact NOT active unit is
OFF
With contact active unit is
ON
in heat pump mode
With DI contact active, unit works in heat pump mode. The capacity steps, if available, will be called by DI
configured as
Capacity step x demand digital input
(x can be 1 to 16)
.
With DI contact active, user can switch ON/OFF the unit by the keyboard. If the unit has been switched-off
from the Visotouch, user can re-start it by deactivate and re-activate the digital input.
Working error
If two digital inputs are configured as cooling request and heating request with both inputs active at the same
time, the unit will be positioned in OFF mode.
