4.26 Pb Troubleshooting

Digital display output

4.26.1

Description

4.26.2

Water side heat exchanger anti-freeze protection.

M-Thermal Split stops running.

Error code is displayed on hydronic box main PCB and

ANTI.FREEZE

icon is displayed on user interface.

Possible causes

4.26.3

Normal system protection.

Temperature sensor not connected properly or has malfunctioned.

Hydronic box main PCB damaged.

Procedure

4.26.4

Outdoor ambient temperature

3°C and water side heat

exchanger water outlet temperature/water inlet
temperature/backup electric heater outlet water
temperature 5

Water side heat exchanger water outlet temperature/water
inlet temperature/backup electric heater outlet water
temperature 2

Yes

Normal system protection. The

system will resume

automatically

Water side heat exchanger water outlet temperature sensor,

water inlet temperature sensor or backup electric heater outlet

water temperature sensor loose

Yes

Ensure the temperature sensor

is connected properly

Water side heat exchanger water outlet temperature sensor,

water inlet temperature sensor or backup electric heater outlet

water temperature sensor has short-circuited or failed

Yes

Replace the temperature sensor

Replace outdoor main PCB

Notes:

Refer to Part 3, 5.7 Water Side Heat Exchanger Anti-freeze Protection Control .

Final outlet water temperature sensor,

water side heat exchanger water inlet temperature sensor and water side heat exchanger water outlet temperature

sensor connections are port CN6 on the hydronic box main PCB (labeled 10 in Figure 4-2.1 in Part4, 2.2 "Main PCB for Hydronic System").

Measure sensor resistance. If the resistance is too low, the sensor has short-circuited. If the resistance is not consistent with the sensor s resistance
characteristics table, the sensor has failed. Refer to Part 2, 1.2

and to Table 4-5.3 in Part 4, 5.1
