Installation without interior terminals
The ecoGEO heat pumps can also be used in installations that do not have any type of interior terminal to generate request signals.
In these cases, a continuous request can be imposed at the digital input of the unit to activate by selecting the appropriate control
logic in the controller. As a result, the heat pump will run the start / stop cycles according to the temperature control of the circuit
and the outside cut-off temperatures of each service.
6. Start-up
Check the following items before starting up the heat pump. Not doing so could result in poor heat pump operation and/or serious
heat pump damage.
1. All the hydraulic circuits of the installation have been properly filled and bled.
2. The cut-off valves of the hydraulic brine and production circuits are open.
3. An external switch has been installed to cut off all the power supply circuits of the heat pump.
4. The heat pump power supply has the proper voltage and allows sufficient consumption to start up the compressor.
5. The inside room temperature of the home is at least 18ºC. Otherwise, the temperature has to be increased by auxiliary
equipment.
