Wolf COB-2 - Connect the Flue Gas Damper to the Power Supply (Cascade Operation Only); Connecting the Stratification Cylinder

Installation
3066501_201910 WOLF GmbH | 45
Terminal Explanation
LP (PP) Cylinder primary pump
Maximum of 1.5 A per output, no more than 600 VA in total
A1 Programmable output (HG14) 230 VAC, e.g. DHW circulation pump
Maximum of 1.5 A per output, no more than 600 VA in total
E1 Programmable input (HG13), e.g. ue gas damper or room thermostat
E2 5kNTC common sensor = header
Alternative 0-10 V control, e.g. 8V = 80% heating output
The maximum external voltage at input E2 is 10 V. Anything higher will destroy the control
PCB 1(a) = 10 V, 2(b) = GND.
AF 5 k NTC outside sensor
SF 5kNTC cylinder sensor
eBus (WOLF control accessories e.g. BM-2, MM-2, KM-2, SM1-2, SM2-2)
NOTE
Increased electromagnetic interference at the installation site!
Possible control faults.
► Fit screened sensor leads and eBus cables.
► One end of the cable shield must be connected to the PE potential in the control unit.
5.10.6 Connecttheuegasdampertothepowersupply(cascadeoperationonly).
► Open the lower casing cover of the HCM-2.
► Strip insulation from the power cable of the damper motor and signal contact.
► Pull the Rast5 plug from output A1.
► Push the power cable of the ue gas damper motor through the strain relief (insert) and secure.
► Terminate the cores at the Rast5 plug A1 and insert the plug.
► Pull the Rast5 plug from input E1.
► Push the limit switch cable of the ue gas damper motor through the strain relief (insert) and secure.
► Terminate the cores at the Rast5 plug E1 and insert the plug.
► Close casing cover.
5.11 Connectingthestraticationcylinder
► Set the ON/OFF switch of the cylinder primary pump to constant pressure (Fig. 6.3 Cylinder primary
pump).
CirculationinconjunctionwithTSstraticationcylinder
The circulation control system of the heat generator prevents the stratied water from mixing during draw-
off and charging.
► Connect the circulation to the programmable output of the heat generator.
