2.4 Circulation option (thermostat variant)
Control of circulating pump (thermostatic)
Within a given time frame (timer WT), the temperature of
the hot water pipe is monitored using the T-C sensor. If this
temperature falls below the adjusted minimum temperature
(Circ. min), the circulating pump is activated. It is switched
off when the temperature of the hot water in the pipe has
increased by the heating hysteresis (Circ. hyst.).
