Enabling the Use set for enabling units you change the behavior of
the temperature control of individual units.
The boiler, if enabled (Enable boiler), can be managed in integration
(Boiler mode: INTEGRAL.) Units sequenced or replacement (Boiler
mode: SUBST.).
In the operation to replace the units in the network will be forced off
below the set temperature in the mask relative to the set of activation
of the boiler (Set menu point). The boiler will be deactivated and
reactivated the unit when the outside air temperature ascend above the
set point. The values of the differential and the dead zone you set in the
menu Service->Service settings->Termoregulation:
Any pumps connected to the sequencer must be declared in the mask.
The option ALWAYS ON turns on and off the pumps at the same time
the ignition on and off the sequencer while selecting ON DEMAND
the request for switching on and off of the pump is by reading the
required pump via bus. The pump will be activated on the rst request
to a network drive and pump will be turned off when no network drives
require more power the pump. With this option are guaranteed the
correct timing of pre and post-circulation circulation, regardless of the
on/off status of the sequencer.
For all pumps declared present (evaporator, condenser, recovery)
you should specify the number of pumps (1 or 2) and the number of
attempts before raising the alarm no ow).
The use of the virtual band is only necessary on some older drives.
By activating the unit / pump at set off the system power off completely
(by stopping in addition to compressors also fans and pump) units that
have reached the set point. To allow a correct reading of the temperature
sensor at least one of the units (choice of Last OFF - the last one that
has been extinguished or Last ON - which is the last game) will activate
the circulation pump. Consult Rhoss Spa before activating this option.
Press again to access the screens to set the model of the single
network units.
Type of unit Unless otherwise stated by Rhoss
S.p.a. Always use Rhoss Chiller for cooling only
units or heat pump and chiller Rhoss EXP for multi-
purpose units.
Enabling / disabling recovery.
Only for EXP units
Choice of conguration recovery sequenced or not
sequenced. See hydraulic diagrams on page 17.
Only for EXP units
Presence or absence of the electronic expansion
valve on the unit. If the EEV is declared present the
relevant data (open, overheating) will be reported in
the Input / Output menu.
