⇒
Heater Circuit Water Pressure is Inadequate
There is no adequate water in the heater system. In this case
led blinks and
led lights steadily.
Solution:
Primary circuit water pressure is checked. If it is below 0.8 bars, water pressure is increased / described
to the customer. If the water pressure is above 0.8 bars, operation of the circulation pump is checked. If it is operating,
before checking primary circuit flow control pressure switch it is provided that there is no air in the primary circuit within
the boiler. If the flow control pressure switch still cannot cut off the contact after the air is discharged, circulation pump
rotation speed, flow control pressure switch diaphragm, flow control pressure switch contacts are checked in this
order. Any defective part is replaced. If 0Ω (closed circuit) is seen at flow control pressure switch and the failure
continues while 0Ω (closed circuit) is seen at P3 socket ends no. 4-7, main card is replaced.
⇒
Usage Hot Water Sensor Failure
It means hot usage water sensor is short circuited or operating improperly. In this case
and
leds blink
together.
Solution:
Hot usage water NTC heat sensor is checked. If 10ºC = 15 kΩ, 20ºC = 12 Ω, 40ºC = 5.7 kΩ, 60ºC = 3 kΩ
values are not read, heat sensor is replaced. In case these values are read, measurement at main card P5 ends no.
1-6 is made. If the value cannot be read, connection cable is replaced / repaired. If correct values can be read, main
card is replaced.
⇒
Heater Circuit Sensor Failure
It means heater circuit sensor is short circuited or operating improperly. In this case
and
leds blink
together.
Solution:
Primary circuit (heater) NTC heat sensor is checked. If 10ºC = 15 kΩ, 20ºC = 12 Ω, 40ºC = 5.7 kΩ, 60ºC
= 3 kΩ values cannot be read, heat sensor is replaced. In case these values are read, measurement at main card
P2 ends no. 3-4 is made. If the value cannot be read, connection cable is replaced / repaired. If correct values can
be read, main card is replaced.
