1.15 Changeable Digital Inputs
Selecting local or
remote cool/heat
control User parameter
h0b
in combination with the remote cool/heat selection switch (installed by the
customer) allows the user to select cooling or heating mode without using the
D
or
C
key on
the controller.
■
When user parameter
h0b
is set to
0
(=not active), cooling or heating mode is determined by means
of the controller.
■
When user parameter
h0b
is set to
1
(=active), cooling or heating mode is determined by means of
the remote switch.
REMARK:
■
This is only in case
p09
(changeable digital input selection S7S) has value 9 (default value).
■
In case dual set point function is selected for this function (
p09
=13), the remote cool/heat control
is not activated, meaning the
D
or
C
keys on the controller are still active.
Selecting local or
remote on/off
control User parameter
h07
in combination with the remote on/off switch (installed by the customer) allows the
user to switch the unit on without using the
D
or
C
key on the controller.
■
When user parameter
h07
is set to
0
(=not active), the unit can only be switched on by means of
the
D
and
C
key on the controller.
■
When user parameter
h07
is set to
1
(=active), the unit can be switched on or off as follows:
■
When the remote on/off switch is opened, the unit is switched off and it is not possible to switch
the unit on/off by pressing the
D
or
C
key on the controller (5 sec.)
■
When the remote on/off switch is closed, the unit is switched on and it is possible to switch the
unit on/off by pressing the
D
or
C
key on the controller (5 sec.)
REMARK:
■
This is only in case
p34
(changeable digital input selection S9S) has value 23 (default value).
■
In case dual set point function is selected for this function (
p34
=13), the remote on/off control is not
activated.
Selecting dual
setpoint control User parameters
p09
(changeable digital input selection S7S) and
p34
(changeable digital input
selection S9S) can be used to assign the dual setpoint control to S7S or S9S.
There are 3 different controls available for 2 different changeable digital inputs (S7S and S9S):
■
p09
: changeable digital input selection S7S
■
0=no function
■
9=remote cool/heat
■
13=remote dual setpoint
■ p34
: changeable digital input selection S9S
■
0=no function
■
13=remote dual setpoint
■
23=remote on/off
When the dual setpoint switch is open, the first setpoint is activated (
r01
cooling setpoint or
r03
heating
setpoint, depending on cooling or heating operation).
When the dual setpoint switch is closed, the second setpoint is activated (
r21
cooling setpoint 2 or
r22
heating setpoint 2, depending on cooling or heating operation).
