Carrier SmartView - Hydronic Kit Option

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 Conguration menu.
2. Select Pump Conguration (PUMPCONF).
3. Set Pump Auto Rotation Delay [pump_del].
Pump Auto Rotation Delay [pump_del]
24 to 3000h 48h
6.5.4 - Customer pumps conguration
Contrary to units with internal pumps, units with customer pumps
may have only variable speed pump.
Customer pumps may be congured as follows:
Pump available Pumps sequence (PUMPCONF)
No pump 0 (no pump)
One single speed pump 1 (one pump only)
Two single speed pumps 2 (two pumps auto)
3 (pump#1 manual)
4 (pump#2 manual)
One variable speed pump 1 (one pump only)
Units with customer pumps are tted with the ow switch, allowing
for the water ow control. For more information about actuators,
see Water ow switch in section 3.9.
IMPORTANT: The variable speed pump can be set only by
Carrier service.
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 tted with two pumps, the rst 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 Conguration
menu (Pump Sticking Protection, PUMPCONF – Pump
Conguration).
To set periodical pump quick start
1. Navigate to the Conguration menu.
2. Select Pump Conguration (PUMPCONF).
3. Set Pump Sticking Protection [pump_per].
Pump Sticking Protection [pump_per]
No/Yes Yes
6.5.6 - ECO pump mode
When the unit is in Standby mode (heating or cooling demand is
satised), the SmartView control may be congured to stop the
pump periodically in order to save energy.
This option can be congured only by service technicians.
To verify the Eco Pump conguration
1. Navigate to the Main menu.
2. Select Miscellaneous Status (MSC_STAT).
3. Verify Eco Pump Mode Active [m_ecopmp].
Eco Pump Mode Active [m_ecopmp]
No/Yes Yes
6.6 - Hydronic kit option
The hydronic kit option allows for continuous monitoring of the
water ow rate (PUMPSTAT – Pump Status).
The hydronic kit provides the option to measure the following
parameters:
■ Inlet and outlet water pressure.
■ Water exchanger ow rate.
The water ow 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 ow rate. Water ow control can be based on
compressor usage, constant delta pressure or constant
temperature difference.
