OTHER SETTINGS
H0 Serial address
H1 Particular configurations: IR32S, IRDRSE/S0 and IR32Y
H2 Possibility of changing parameter set from keypad (0=no, 1=yes)
H3 Remote commander readiness code
Note: for the set times to become operative, the instrument must be switched off and on again.
H0: Serial address
It allows equipment to be provided with an address to which it will respond when connected to a control or
remote assistance system. Also known as serial or network connection. Default: H0=0; Available on all
models.
H1: Special configurations
This parameter allows particular functions which vary with different models to be defined. These are:
IR32S, IRDRSE/S0: the IR32S can operate as a simple thermostat (H1=0 is set in the factory), or as a
thermostat and defrost controller for static units at normal temperature (defrosting by shut-down of
compressor, H1=1). If the second type of operation is required, it is necessary to change the unit's
configuration by setting H1=1. Default: H1=0, thermostatic operation.
IR32Y: the IR32Y is a thermostatic model with defrost control for static low temperature units. Defrosting can
be effected by time ("X" operation) or can be initiated on the evaporator reaching the requested temperature
("Y" operation). In this second case it is necessary to fit the equipment with a second sensor, known as the
"defrost sensor". By setting parameter H1, X or Y operation can be selected. With H1=0 (the value set in the
factory), the equipment operates in the X mode (defrost by elapsed time). To choose Y mode (defrost by temperature)
H1=1 must be set. Default: H1=0, mode X operation.
IR32P, IR32C and IRDRC: decides whether the fourth relay is used as an auxiliary output (for lighting, anti-
mist fan or other on/off function) or as an alarm output.
In the first case (auxiliary output) it is possible to start and stop the item connected by pressing
the relay is connected to the equipment's light it is possible to switch it on and off not only by pressing the
button, but also automatically when the door is opened or shut by connecting the door switch (see parameter
A4). In the second case the relay signals any alarm situations, allowing a siren or other remote alarm
indicator to be activated. The possibilities are: 0 = auxiliary output; 1 = alarm output. Default: H1=1, alarm
relay.
H2: Inhibit the Keypad and/or the Remote Control
Using H2 parameter is possible to prevent modification of the SET POINT and every parameters, when the
controller is exposed:
Parameter
If the Keypad is inhibited it is no possible to modify SET POINT and the "F" parameters, but it is possible
to visualise their value. "C" Parameters, accessible by means of a password, can be modified also with the
procedure above described. With the remote control inhibited it is possible only to visualise the value of
parameters, but no change them.
Note: if H2 is setted to "2" or "3" by the remote control, it is immediately inhibited (pushing "MEMO" button is
not required). To enable again the remote control, set H2 to "0" or "1" using the keypad
H3: Remote programming enabling0 code
Parameter H3 allows an access code to the control. As already indicated, this makes use of the remote
control possible when there are several controls on the same panel without danger of interference. For more
detail, see the section on remote programming. Default: H3=00, parameters can be changed from the
keypad. Available on all models.
Note: see the following chapter "Notes for the new release" to a more detailed description of this parameter
