LOG TIME Time interval between collection points of temperature history in minutes.
The history graphs always show the 60 last collection points, which means that the graphs can display history
from 1 hour up to 60 hours ago.
(The function is not active if there is an active alarm).
Factory setting: 1M, range: 1M – 60M
8.9 DEFROST
It is important to know the source where the energy for defrosting is
taken when finding a min. flow. If the parameter ENERGY PR. H.W. is
OFF, the energy is taken from the heating system. If the parameter is
ON, the energy is taken from the water heater.
Parameter Meaning
COMPR. STOP
Factory setting: , range: – ON
ENERGY PR.H.W Prioritized energy source is hot water when defrosting.
Factory setting:
, range: – ON
8.10 OPTIMUM
Parameter Meaning
START FLOW CIRC. Setting the speed which a speed controlled condenser pump must start with.
Check using MANUAL TEST -> CONDENSER PUMP which speed gives sufficient flow. This is indicated by ”F”in
the display (flow sensor closed).
The start flow is maintained one minute before control goes to speed control the condenser pump.
Factory setting: 70%, range: 30-100%
IDLE FLOW Flow when there are no demands active. If it's an EQ system this setting applies for the circulation pump. The
condenser pump will then always have the setting 30% idle flow.
Factory setting: 50%, range: 30-100%
MAX FLOW HEAT Maximum flow allowed accros the radiator circuit. If it's an EQ system this setting applies for the circulation
pump. The condenser pump will then always have the setting 100% max flow.
Factory setting: 90%, range: 30-100%
FLOW FACTOR
HEAT (N/A for iTec
XT Total EQ)
Indicates the relation between condenser flow and compressor power (see topic "FLOW FACTOR" under chapter
"Tuning the system").
Factory setting: Factor 1,0, range: 2,0-2,0
MIN FLOW HEAT Minimum condenser flow allowed during heat production for home and pool heating.
Factory setting: 80%, range: 30-100%
MIN FLOW H.W Minimum condenser flow allowed during hot water production.
Factory setting: 80%, range: 30-100%
