10.5.9 Drying screed without the heat pump outdoor unit.
The indoor module can be used for drying screed using the electrical
back-up in forced operation mode. It is not necessary to connect the out
door unit.
1. Switch on the heat pump and activate the screed drying function.
2. Adjust the parameters for screed drying.
3. Force the electrical back-up by increasing the value of the HP000
parameter.
10.5.10 Supplying the heat pump with photovoltaic energy
When lower cost electrical energy is available, such as photovoltaic ener
gy, the heating circuit and domestic hot water tank (if present) can be
overheated. Underfloor cooling cannot be supplied with power in this way.
To activate this functionality, enter data for the AP001 parameter and con
nect a dry contact to the BL1 input or the AP100 parameter and a dry con
tact on the BL2 input.
Tab.64 Voluntary overheating parameters
Parameter
Description
AP001 or AP100
Hydraulic back-up: 8 (Photovoltaic with heat pump only)
Electrical back-up: 9 (Photovoltaic with electrical back-up)
HP091
Offset temperature of heating setpoint when photovoltaic function is activated
HP092
Offset temperature of DHW setpoint when photovoltaic function is activated
10.5.11 Connecting the installation to a Smart Grid
The heat pump can receive and manage control signals from the "smart"
energy distribution network (Smart Grid). Based on the signals received by
the terminals of the BL1 IN and BL2 IN multifunction inputs, the heat pump
shuts down or voluntarily overheats the heating system in order to opti
mise electricity consumption.

1. Connect the Smart Grid signal inputs to the BL1 IN and BL2 IN in
puts on the EHC–04 PCB. Smart Grid signals come from dry con
tacts.
Germany: Connect the SG1 and SG2 terminals respectively from the
electricity meter to the BL1 IN and BL2 IN inputs on the EHC–04
power circuit board.
2. Set the AP001 and AP100 parameters to 10.
The heat pump is ready to receive and manage Smart Grid sig
nals.
