Flow Switch Control
A paddle flow switch is installed into the water pipe work of the unit to warn of low water flow within the system.
The flow switch limitations are as follows:
Flow switch setpoint Flow rate
Setpoint increasing flow “ON” 0.28 l/s
Setpoint decreasing flow “OFF’” 0.24 l/s
After 5 retries of start-up of pump, with the paddle flow switch, which stays opened, the alarm 32 activates.
8.3. Override List

8.3.1. SYSTEM MODE OVERRIDE [P047]
In certain cases, the control system may override the currently running operating mode in order to
optimize the performance of the unit.
The control system may employ the following overrides:
# Override Remarks

11 Off Peak Compressor and electric heaters are not allowed to run
12 Solar Production
Unit is not allowed to run in Heat Mode or DHW Mode because hot water is
produced by a solar system.
13 Summer mode Unit is not allowed to run in Heat Mode because summer mode is active.
