6 - STANDARD CONTROL OPERATIONS AND OPTIONS
6.5.3 - Automatic pump selection
If two pumps are controlled and the reversing function has been
selected (PUMPCONF – Pump Configuration), the control
balances the pump run time to match the configured pump
changeover delay. If this delay has elapsed, the pump reversing
function is activated.
To set pump automatic rotation delay
1. Navigate to the Configuration menu.
2. Select Pump Configuration (PUMPCONF).
3. Set Pump Auto Rotation Delay [pump_del].
Pump Auto Rotation Delay [pump_del]
24 to 3000h 48h
6.5.4 - Customer pumps configuration
Units fitted with external pumps may be of fixed speed or variable
speed type.
Customer pumps may be configured as follows:
Pump available
No pump
One pump (fixed or variable speed) 1 (one pump only)
Two pumps (fixed or variable speed)
Units with customer pumps are fitted with the flow switch, allowing
for the water flow control. For more information about actuators,
see Water flow switch in section 3.7.
6.5.5 - Pumps protection
The control provides the option to automatically start the pump
each day at 14:00 for 2 seconds when the unit is off.
If the unit is fitted with two pumps, the first pump is started on even
days and the second pump is started on odd days. Starting the
pump periodically for a few seconds extends the lifetime of the
pump bearings and the tightness of the pump seal.
Periodical pump quick start can be selected via the Configuration
menu (PUMPCONF – Pump Configuration).
To set periodical pump quick start
1. Navigate to the Configuration menu.
2. Select Pump Configuration (PUMPCONF).
3. Set Pump Sticking Protection [pump_per].
Pump Sticking Protection [pump_per]
No/Yes Yes
Pumps sequence (PUMPCONF)
0 (no pump)
2 (two pumps auto)
3 (pump#1 manual)
4 (pump#2 manual)

6.6 - Hydronic kit option

The hydronic kit option allows for continuous monitoring of the
water flow rate (PUMPSTAT – Pump Status).
The hydronic kit provides the option to measure the following
parameters:
■ Inlet and outlet water pressure.
■ Water exchanger flow rate.
The water flow rate is based on the pressure difference between
the inlet and outlet pressures and the pressure drop curves.
Hydronic kit option with variable speed pumps
For units with variable speed pumps, this option allows for the
automatic adjustment of the pump speed necessary to maintain
the correct water flow rate. Water flow control can be based on
compressor usage, constant delta pressure or constant temperature
difference. For more information on variable speed pumps control,
see also section 6.5.1.

6.7 - User quick test

The Quick Test functionality allows users to test and verify if certain
components of the unit behave correctly (only logged-in users can
activate the Quick Test).
To enable Quick Test
1. Navigate to the Main menu.
2. Select Quick Test 1 (QCK_TST1). The menu can be accessed
when logged in at user access level.
3. Set Quick test Enable [QCK_TEST] to "yes".
Quick test Enable [QCK_TEST]
No/Yes Yes
IMPORTANT: To enable the Quick Test functionality, the unit
must be stopped (Local off mode).
Once the Quick Test functionality is enabled, it is possible to test
parameters such as fans' outputs, pumps' commands, etc.
For more details, please see the Quick Test 1 table description
(QCK_TST1 – Quick Test 1) in section 5.1.
