Special design information
• The DHW temperature sensor and the cylinder primary
pump are connected at the terminals inside the
fig. 46,
appliance and configured via the MEC2 programming
unit.
• For the appliance, enable "Boiler with pump and low
loss header" at the MEC2 programming unit.
• In combination with a low loss header, the integral
pump in the Logamax plus GB162 must be controlled
subject to output (setting 0).
• For the Logamax plus GB162-45, order the integral
pump as an accessory.
• For the Logamax plus GB162-50, order an external
high efficiency pump UPM 15-70 with safety set.
