Page 17: Insulation Of Pump Housing
The heat loss from the pump and pipework can be reduced by insulating the pump housing and the pipe with the thermal insulation shells supplied with the circulator (supplied as standard only with model ES2 ADAPT) → Fig. 7.5. CAUTION Do not insulate the control box or cover the control panel. -
Page 18: Electric Connection
ENERGY SAVING 8 Electric connection The electric connection has to be performed by a qualified electrician in compliance with the national regulations. Follow the safety regulations and installation regulations of your country. Connection to the power supply must be carried out in compliance with the standards via a fixed power cable which is fitted with a plug-type connection or an all-pole isolating switch with a minimum contact opening of 3 mm. -
Page 19: Commissioning
For cables with outer min. Ø 7.0 mm max. Ø 8.5 mm diameter of the sheath between 7 mm and 8.5 mm: remove the rubber retainer from the cable gland. In this case, the circulator can only be installed with the cable gland down. -
Page 20: Automatic Detection Of The Presence Of Air - Vent System
ENERGY SAVING 9.3 Mode of operation A LED provides information about the operation status of the circulator. COLOR DESCRIPTION ActiveADAPT mode The activeADAPT mode enables the circulator to actively adapt its performance to the demands of the system during Violet short control intervals inside a defined control area. - Page 21 9.4 Automatic detection of the presence of air - Vent system 10 min Fig. 9.2: Filling and venting of heating systems Fill and bleed the system correctly. The circulator can be noisy at start due to the presence of air. Such noise should stop after few minutes of operation. Usually the pump rotor chamber normally bleeds automatically after a short time in operation.
- Page 22 Modify the performance of the circulator (head) as needed by rotating the selector using a flat screwdriver, as given in the following table. The selection of the right functioning curve depends on the characteristics of the heating system in question and the actual heat demand. MODEL ES2 ADAPT ES2 SOLAR ES2 PURE activeADAPT *...
