Main circulation pump speed regulation (optional)
The internal basic input/output module MD1 with the appropriate choice of circulation pump type offers
linear speed adjustment of water flow. The circulation pump M3 with built-in control input is connected
to the digital output Q3. Setting the speed is enabled by connecting the PWM pump input and PWM - /
PWM + outputs on the internal basic V/I module MD1.

Connecting heating cycle 2 (direct cycle - optional)
Connect the circulation pump M5 from mixing cycle 1 to connecting clamp of the digital output Q7. The
cycle is controlled via room thermostat signal between GND and D6 (picture below) or room corrector
KT-1(2) signal (chapter 3.5) or via weather curve.
