11.1 Information messages
Information messages are displayed when appropriate and are intended to
inform users about various operational situations.
Start delay
The compressor is not allowed to start too quickly when it has stopped. The
delay is usually at least 10 minutes.
Heating off, radiator sys
Shows for each heating system that the product is operating in summer
mode when only hot water is required, not heating.
Ripple control
Shows that ripple control is active. Ripple control is a device which an
electricity supplier can fit with the aim of disconnecting high current draw
equipment for a short period of time. The compressor and electrical power
are blocked when ripple control is active.
Tariff, HP off.
Shows that Tariff HP is not active. Should always be “Off”.
Tariff, EL, off.
This is used when a dual tariff is used with lower energy costs at set hours of
the day. The heat pump can then take advantage of reduced primary energy
costs. Should always be “Off”.
Compressor blocked
The compressor is set to be shut down, e.g. before drilling or digging
has been carried out for the collector loops. The product comes with the
compressor switched off. This option is selected under the
Installer/Settings/
Heat pump 1, 2 and 3
menu.
High current, reduced electricity (xA)
The property’s main fuses are overloaded due to the fact, for instance, that
several appliances requiring power are being used simultaneously. The
product reduces the electric heaters’ electrical output over time.
