2.12. Configuration of remote control options
EVU/SG control
1. Used to enable the EVU electrical consumption control. The EVU control prevents
production of energy with the compressor or the auxiliary equipment. Circulator
pumps, valves and other components can be activated to consume energy from the
storage systems.
2. Used to enable the SG states control. If SG control is enabled, it is not possible to
enabled the EVU control and vice versa. Depending on the value of the digital inputs,
we distinguish four operating states SG:
SG1 [0 0] (Normal status): The heat pump operates normally according to their
configuration.
- SG2 [0 1] (Reduced tariff): We are in a reduced tariff period, so we will take
advantage of the lower price of electricity to change heat pump setpoints and
produce more heat and cold.
-SG3 [1 0] (Locked status): The heat pump sends a compressor lock signal to the
heat pump, but production surpluses can still be used by activating or
deactivating the non-critical loads configured.
- SG4 [1 1] (Forced status): The heat pump will force the maximum possible
consumption in the installation to help balance the grid.
These external signals can be sent by the electric company itself to try to keep the
distribution network balanced at any time.
3. Used to select the desired digital input for EVU signals or SG signals.
4. Used to select the operation logic of the EVU / SG control.
a.
NO: Closed contact to activate EVU control. SG control is a 0 with open contact.
b. NC: Open contact to activate EVU control. SG control is a 1 with open contact.
SG2 Mode
1. Used to adjust the temperature differential for each service on the heat pump
setpoints, when the stat SG2 "Reduced tariff" is active.
