8 - STANDARD CONTROL OPERATIONS AND OPTIONS
8.1 Unit Start / Stop control
The unit state is determined based on a number of factors,
including its operating type, active overrides, open contacts,
master/slave configuration, or alarms triggered due to operating
conditions.
The table given below summarises the unit control type [ctrl_typ]
and its running status with regard to the following parameters:
ƒ
Operating type: This operating type is selected using the
Start/Stop button on the user interface.
ƒ
Start/stop force command [CHIL_S_S]: Chiller start/stop
force command can be used to control the chiller state in
the Network mode.
- Command set to stop: The unit is halted.
- Command set to start: The unit runs in accordance
with schedule 1.
ƒ
Remote start/stop contact status [Onoff_sw]:
Start/Stop
contact status can be used to control the chiller state in the
Remote operating type.
ƒ
Master control type [ms_ctrl]: When the unit is the master
unit in a two-chiller master/slave arrangement, the master
unit may be set to be controlled locally, remotely or via
network.
ƒ
Start/stop schedule [chil_occ]: Occupied or unoccupied
status of the unit.
ƒ
Network emergency stop command [EMSTOP]:
If activated, the unit shuts down regardless of the active
operating type.
ƒ
General alarm: The unit shuts down due to failure.
8.2 Heating / Cooling control
AQUACIAT POWER heat pumps and chillers fitted with a boiler
may operate in cooling or heating mode. The CONNECT
TOUCH control determines whether the unit is in the heating or
cooling operating mode.
ƒ
Without a boiler, the chiller remains in Cooling mode
(Heating is NOT possible).
ƒ
Heat pumps may operate in Cooling or Heating mode,
depending on current configuration.
When the chiller is in Heating mode , the control utilises the
boiler to satisfy the heating demand. For heat pumps, the boiler
is used when mechanical heating is impossible or insufficient.
Additionally, when the outside air temperature is very low,
electric heaters can be used as a form of supplemental heating
(heat pumps only).
When Cooling mode is selected, the unit will operate in the
Cooling mode and, as a result, the boiler or electric heating will
not be activated.
The unit may also "operate" in Standby mode which means that
it is neither cooling nor heating. If the unit is in Standby mode ,
it does not cool or heat and compressors are stopped. The
pump is running with no mechanical cooling or heating unless
configured otherwise. The pump may be stopped depending
on pumps configuration (PUMPCONF – Pump Configuration).

IMPORTANT: When the unit is stopping or there is a demand
to stop the unit, compressors are stopped consecutively.
In case of emergency stop, all compressors are stopped at
the same time.
