4.5. Source control
It is possible to control four independent sources. The electrical connections for controlling each source are as follows.
Source 1:
Geothermal
Source alarm signal input
Activation of the pump or valve of the source
--
Pump regulation
Source inlet temperature sensor
Source 2:
Geothermal
Source alarm signal input
Activation of the pump or valve of the source
--
Pump regulation
Source inlet temperature sensor
Source 3:
Geothermal
Source alarm signal input
Activation of the pump or valve of the source
--
Pump regulation
Source inlet temperature sensor
Source 4:
Geothermal
Source alarm signal input
Activation of the pump or valve
--
Pump regulation
Inlet temperature sensor
