LIST OF VALVE PARAMETERS
(to switch parameters and change setting – turn the knob):
E1
M
aximal temperature behind
the
valve
(s
etting maximal temperature behind valve E1a, E1b or E1c below
corresponding E2a, E2b or E2c
[
minimal temp. behind valve
]
results in both settings becoming equal
)
E1a day (1-99°C, default: 45°C)
E1b night (1-99°C, default 30°C)
E1c economy (1-99°C, default: 25°C)
E2
Min
imal temperature behind
the
valve
(s
etting minimal temperature behind valve E2a, E2b or E2c above
the corresponding E1a, E1b or E1c [max temp. behind valve] results in both settings becoming equal
)
E2a day (1-99°C, default: 35°C)
E2b night (1-99°C, default 20°C)
E2c economy (1-99°C, default: 15°C)
E3 Minimal temperature of the boiler return pipe regulated by the valve
(
40
-
55
°C, default: 5
0
°C)
E4
Valve downtime (valve action time is constant - 1 sec.) (0-200 sec., default setting: 10 sec.)
E5
Manual valve mode (the [STOP] button switches off the manual mode)
E
6
Direction of valve turning (press [EDIT] and confirm to reverse direction of turning of the valve
)
CAUTION: return to default settings will not change direction of valve turning
.
When boiler temperature at the return is lower than parameter E3, the valve is closed. When temperature at
the return is equal to the E3 setting, the valve remains closed. The controller allows to open the valve only
when temperature at the return is higher than the E3 setting.
Over the first 6 hours after the FIRE UP precedure has been started the controller does not take into account
the minimal temperature at the return to the boiler.
When hot water tank priority has been selected (parameter F3 set to "YES"), over the first 3 hours from
switching on the C.H. pump the controller does not take into account the minimal temperature at the return to
the boiler.
