9.1.6 CTC EcoLogic system 1 – Solar energy
Solar panels can be connected to the boiler using a diverting valve (Y31), or
to a ground heating loop in order to recharge the bedrock/ground.
The speed-controlled pump (G30) and sensors B30 and B31 are itted next
to the solar panels.
For recharging the bedrock/ground, a diverting valve (Y31), heat exchanger,
charge pump (G31) and non-return valve are connected.
When the recharging function is in operation, the CTC EcoLogic also starts
the brine pump in the heat pump (CTC EcoPart). The charge pump for
recharging the bore hole (G31) ensures there is suficient low through the
heat exchanger.
The speed-controlled pump (G32) and a heat exchanger are itted for
charging the hot water.
