Root cause category: component – electrical
Possible failure Root cause Check Repair
3‑way valve blocked. Component failure. Check the 3‑way valve. Replace the 3‑way valve.
Root cause category: system design
Possible failure Root cause Check Repair
Water circuit – requested
capacity too high.
Incorrect system selection. Check required capacity by
heat load calculation. See
the capacity tables in the
engineering data book to
know max. system capacity
at indicated conditions.
Adapt system design.
Water circuit - water
volume too big.
▪ Long water piping,
▪ Too many heating
emitters.
Check required capacity by
heat load calculation. See
the capacity tables in the
engineering data book to
know max. system capacity
at indicated conditions.
Adapt system design.
Water circuit - pressure
drop too big.
▪ Too small water piping,
▪ Too long water piping,
▪ Too many heating
emitters.
Compare the pressure
drop of the total system
with the water pump
characteristics (See check
of water pump). Decreased
water flow will cause a
drop in capacity.
Adapt system design.
2.4.12 Symptom: Inaccurate temperature control
Root cause category: parameter (setting)
Possible failure Root cause Check Repair
Incorrect setting of unit
control method (setting
[C‑07]).
Incorrect setting of unit
control method (setting
[C‑07]) (leaving water
control, room thermostat
control, ext. room
thermostat control).
Check if setting [C‑07]
(leaving water control,
room thermostat control,
ext. room thermostat
control) is set according to
the application.
Adjust setting to match
application.
Incorrect setting of pump
operation mode
(continuous, sample,
request) (setting [F‑0D]).
Incorrect setting. Confirm setting [F‑0]. Adjust setting [F‑0] if
required. (Factory setting:
[F‑0]=1).
Root cause category: installation
Possible failure Root cause Check Repair
User interface –
thermostat sensor value
NOT representing room
temperature.
Bad location of thermostat
sensor (external influence)
in case of room thermostat
control (setting [C‑07]=2).
Check if user interface is
mounted in the correct
position to measure the
correct room temperature.
Correct the position of the
user interface for more
accurate room
temperature
measurement.
