H8: Select light or AUX output to activate with time band.
This parameter can be used to select the output that is activated or deactivate according to the time band
(see parameters tON and tOF).
H8=0=> Time band linked to output confi gured as the light.
H8=1=> Time band linked to output confi gured as AUX.
Note: the output being controlled (light or AUX) must be available and selected with parameter H1.
Default: H8=0 => Time band linked to the light.
H9: Enable set point variation with time band.
This parameter can be used to enable the variation of the set point according to the time band (see
parameters ton and toF). The controller modifi es the set point by adding the value of parameter r4 (to
the time toF), the new value is used for all the functions relating to the set point (e.g. relative high and
low temperature alarms, control with dead band, control with two compressor steps etc.).
H9=0 => Set point variation with time band disabled.
H9=1 => Set point variation with time band enabled.
Note: When r4=3.0 (preset value) the set point is increased by 3 degrees from the value used before
toF, at ton the value of the set point will be the value set for parameter St.
As the time band set by ton and toF is related to the output auxiliary selected using parameter H8, the
corresponding output will switch on at ton, and will switch off at toF.
Therefore, when H9=1, the following will be true:
- ton : normal set point and selected output on.
- toF : set point + r4 and selected output off.
Default: H9=0 => Function disabled.
HPr: Print profi le (masked parameter)
This is used to select the required profi le for printing the report on an external printer.
The interface for printing the data from the instrument requires a specifi c accessory.
Default: HPr=0 => Report printing disabled.
Hdn: Number of sets of default parameters available
The controller can feature one or more sets of default parameters. Set 0 is standard and cannot be custo-
mised. The other sets can be customised by the user with the programming key kit PSOPZPGR00.
Set Customisable Note
0 NO The levels of visibility are not modifi ed. Sets the values of the
visible parameters only.
1YES
2
3
4 The levels of visibility and the values of all the operating and
unit parameters are set.

Notes:
1. The set of customisable default parameters can only be used on the controller if there is suitable
hardware (expanded EEPROM memory).
2. If when loading a set of customised default parameters there is an EF EEPROM error (memory error
on the controller), the previous parameters can be restored by switching the instrument off and on
again.
3. If there is an EF EEPROM error, to maintain the loaded parameters, enter parameter confi guration
mode, check the values then save them to the EEPROM using the special procedure. At then end of
the operation, the EEPROM error signal will be cancelled.
4. If there is a recurring EE or EF EEPROM error when loading a set of customised default parameters,
the EEPROM on the instrument should be corrected using the programming hardware key.
5. After loading a set of customised default parameter, the controller automatically updates the me-
mory, saving both the levels of visibility and the values of the parameters.
6. The parameter Hdn must have the same value in all the sets of customised default parameters.
7. For greater protection, parameter Hdn must be set to not visible.
Default: Hdn=0 => standard default parameters only.
Hdh: Anti-sweat heater offset
This represents the offset from the set point for the anti-sweat heater function. If Hdh = 0, the anti-
sweat heater function is disabled. The anti-sweat heater function is used to maintain the aux1 output,
confi gured as the light or aux (H1= 2, 3, 8, 9) deactivated while the control temperature (virtual probe)
is less than ‘St’ + ‘Hdh’ when the instrument is fi rst powered up, the ‘HI’ ‘IA’ ‘dA ‘CHt’ ‘EE’ ‘EF’ ‘rE’ alarms
are reset.
During the aforementioned alarms, the aux1 output, confi gured as above, is deactivated.
The function is active, if the light or aux functions are set to be deactivated when off ,‘H1’ or ‘H5’=8, 9,
even when switching the controller on.
Default: Hdh =0.0 => function disabled.
