DELTABOOSTER_GB01
Function
The control panel has been built-up as a schematic drawing of the DELTABOOSTER.
A number of warning lamps indicate the operational condition of the plant and any fault
situations. The warning lamps are divided into three categories:
Green: indicates a motor or a valve in operation.
Yellow: indicates an activated sensor (pressure switch, flow switch, level switch).
Red: indicates a serious fault (leakage, overheating, low water level).

If a fault arises, the concerned red light will turn on and the plant stop. The status of the
opereational condition of the machine at the moment the fault arised will be kept until the
current is switched off. Faults on the individual pumps can be by-passed so that the other
pumps can continue their operation. This is achieved by stopping and re-starting the
machine.
Y1 and Y2 turn on when the cold/hot water inlet is open.
Y3 turns on when the relief valve is closed.
E1 and E2 turn on if there is a leakage on the system.
B1 and B2 turn on when the pressure is higher than the setting point of the pressure
switches.
B4 turns on when the flow switches registrate a return of water to tank (over 10 l/min.).
Y4 turns on when the temperature adjustment is on. Flashes if the water supply is insufficient.
E3 turns on in case of an illegal sensor combination. Example: B1 turn on but not B2
(see diagram on page C10).
B7 turns on if the temperature of the water in the water tank is too high, max. 80°C.
B8 turns on if the water level is too low.
B5 and B6 turn on if the water level is either too high or too low.
Mx turns on when the motor pump is in operation.
Qx turns on in the case of an overload or phase breaking (motor protection disconnects).
Kx turns on if the temperature in the windings is too high (over 160°C).
