6.3 Time for function blocking
With this function enabled, setups are protected against unauthorized changes, and thus are available for
viewing only. In this condition, when trying to change these values, the
[LC]
message will be displayed.
To block functions, select any value different from
[no]
(
[15]
to
[60]
) on
[L1]
setup. This is the pressing
time required to validate function blocking. To block the keyboard, press and hold the
%
key for the time set in
[L1]
. To unblock, turn off the controller and then turn it on again. As soon as the
[SF]
message appears,
press the

6.4 Shut down control functions
As control functions are shut down (
[L2]
), the controller starts to operate as a temperature indicator only,
with all outputs deactivated. This function can operate in the following ways:
[,0]
Does not allow control functions to shutdown.
[,1]
Allows the turning on and off of control functions only if the functions are unlocked.
[,2]
Allows the turning on and off of control functions even if the functions are blocked.
To turn the control functions on/off, press and hold the
$
key for 10s, until the
[Ct]
message
appears, and
then release it.
NOTE:
When restarting the control functions, the controller will continue with these functions.

This is the control temperature of the normal operating mode. When the S1 sensor
temperature (ambient) is lower than the configured value for this function, the compressor
will be turned off.
This is the control temperature when the power-saving mode is active. If the S1 sensor
temperature (ambient) is lower than the configured value for this function, the compressor
will be turned off.
Limits preventing the accidental setup of an excessively high or low temperature setpoint,
which could result in high energy consumption by keeping the system turned on.
This is the difference between turning cooling OFF and BACK ON in normal operating
mode.
Example: If adjusted
[t1]
=
[4.0]
and
[h1]
=
[1.0]
, the compressor will be turned
off when the S1 sensor temperature (ambient) is less than
[4.0]
and it will be turned on
when it is higher than
[5.0]
(
[4.0]
+
[1.0]
).
This is the difference between turning cooling OFF and BACK ON in power-saving mode.
