• off : F4.
In the event of condenser probe errors, the condenser fan output, if selected, is activated.
Important:
If no condenser probe is selected, the condenser fan output, if selected, is disabled.
Default: F4=40.0 degrees.
F5: Condenser fan start diff erential
This is the diff erential used to control the condenser fans.
Default: F5=5.0.

Note:
- par. H5 refers to the instruments with 5 relays (ir33DIN, powercompact and MasterCella);
- parameters H7, HPr, Hdn, HrL, HrA, HsA and In are masked and consequently only visible using the programming kit (IROPZPRG00).
H0: Serial address
This is used to assign to the instrument an address it responds to when connected to a supervisory or telemaintenance system.
Default: H0=1.
H1: Operating mode: logic of output AUX1
Establishes whether the fourth relay is used as an auxiliary output.
The following functions can be associated:
H1=0
- alarm output normally energised. The relay is de-energised when an alarm occurs. The AUX output in "alarm" mode can be
set to operate either with the relay energised or de-energised. The latter mode ensures maximum safety, because the alarm is also
activated in the event of power failures or disconnection of the cables.
H1=1
- alarm output normally de-energised: the relay is energised when an alarm occurs.
H1=2
- auxiliary output: the actuator connected can be switched ON/OFF using the AUX button. Switching the actuator ON/OFF
is signalled by the icon on the display.
H1=3
- light output: the light on the unit can be switched on/off when the door is opened, pressing the LIGHT button, enabling the
digital input switch door or the curtain switch digital input (see parameter A4, A, A6) if the door switch is enabled (see parameter
A4). In this case, the light is switched off when the door is closed, unless previously switched off from the keypad. Switching the
light on/off is signalled by the icon on the display.
H1=4
- auxiliary evaporator defrost output: a heater or reversing valve can be controlled to perform an electric heater defrost or hot
gas defrost on the auxiliary evaporator.
H1=5
- pump down valve output: the activation and deactivation of the pump down valve can be controlled.
H1=6
- condenser fan output: if the high condenser temperature alarm is activated, the output can be used to control the condenser
fans (see parameter Ac and F4).
H1=7
- delayed compressor output: the output is activated a few seconds after the compressor starts (the delay is established by
parameter c11, deactivation of the compressor output corresponds to immediate deactivation of the delayed compressor. If this operating
mode is set, it is also active during the compressor pump down and autostart phases, if selected with the appropriate parameters.
H1=8
- auxiliary output with deactivation when OFF: in the off status, the auxiliary output cannot be activated. When starting again,
the auxiliary output returns to the previous status.
H1=9
- light output with deactivation when OFF: in the off status, the light cannot be activated. When starting again, the light
returns to the previous status.
H1=10
- no function associated with the output. In this case, the logical output AUX1 is not used for any function. If logical outputs
AUX1 and AUX2 are associated with the same relay, this setting means the relay in question will only be associated with AUX2.
Vice-versa, using this setting for AUX2, the relay will only be associated with AUX1. This possibility is useful when there is just one
auxiliary relay, and it needs to be used alternatively as a light relay, associated with the light button and icon, or as an AUX relay,
associated with the AUX button and icon.
H1=11- reverse output in control with dead band: used to activate control with dead band ('St' 'rd' 'rn' 'rr'), using the auxiliary output
aux1 for the reverse function.
H1=12
- second compressor step output.
H1=13 -
second compressor step output with rotation .
Important: mode 'H1'=0 is also useful for signalling power failures.
Default: H1=1 => relay energised with alarm active. Available on all models with aux output.
