With the addition of a pump adapter, the combinations may be used for externally closed as well as for externally open heating/cooling jobs (with option level control). Models with Pilot ONE have a speed-controlled pressure-suction pump. The temperature constancy pursuant to DIN 12876 is 0.02 K with the Compatible Control models, and 0.05 K with the MPC models.
