GHE
– the configuration of the Ground Heat Exchanger. The edition is the same as for clock case.
•
config :
OFF
- total turning valve GHE off. The air always taken from the external inlet
•
config :
ON
- the valve is always turned on for taking the air from GHE regardless of temperatures
•
config :
AUTO
– the valve is controlled basing on the temperatures measurementsTo and Tg and Comfort settings
•
config :
AUTO R
– the same as above with the additional option of GHE regeneration
•
comfort :
HEATING
– selecting warmer power source with the air (usually autumn, winter)
•
comfort :
COOLING
– selecting cooler power (usually spring, summer)
•
comfort :
TEMP To
– automatic work depends on outside temperature
BYPASS
– the configuration of bypass. Edition is the same as other functions before.
•
config :
OFF
- total turning the bypass valve off. The air always comes through the exchanger
•
config :
ON
- the valve is always on. The air always bypasses the exchanger.
•
config :
AUTO
– the valve is controlled basing on the temperatures measurements. Te, To, Tg
•
Tout > …°C
- to turn the bypass on, the power temperature Has to be above that value – it is the air temperature of
the external inlet sensor or GHE sensor, depending on the previous setting mode. The range of the setting is [5÷20°C]
•
Textr >…°C –
as above, the extract air from the room must be bigger than that value. The range is [15÷30°C]
DIGITAL INPUT (CFG)
– controller has an input, market on the relay board as WE5. To this input we can connect Any
floating switch such as a relay output of fire protection system, alarm, etc… This option lets you determine how controller should
respond to the appearance of the signal in input. Mode's changes, as in the previous edition. You can choose one out of seven (the
last one is reserved for the water heater HW protection).
•
mode 1 –
Inactive
. Controller does not respond to this input signal.
•
mode 2 –
High Vent,
fans = MAX
. The option can be used for short-term switch to maximum speed for the intensive
ventilation of rooms such as kitchen, bathroom... To control in this mode you should use monostable switch such as
bell switch type. Pressing the switch will cause that controller sets fans to maximum speed for 30 minutes. After this
time the controller will return to normal operation. If you press the switch again during this operation it will cause the
break of the procedure and earlier return to normal mode.
•
mode 3 –
Fire protection
, fan SUPL=STOP fan EXH=MAX
. This mode is intended to cooperate with the fire
protection instalation. When the signal is on WE5 the controller turns off supply air fan and exhaust fan switches to the
maximum speed until the signal from a fire protect. system does not change state.
•
mode 4
–
Stand by
, fans = MIN
. Configuration that can work with home alarm (security) systems. Arming the alarm
system during the absence of occupants, make controller go into the minimum air exchange.
SCHEDULE
– this option allows to programme various ventilator' speeds, suitably for the individuals' needs. In this way for
the every hours of any other day there are various speeds' values. After selecting the "schedule" icon, the controller changes the
main menu screen for the table consisting of graphic presentation of particular configuration. The current value in accordance with
the data and time is highlighted in green. Edition is the same as for the clock. During the edition the values are changed for the
yellow colour.
FAN SPEED
– [they are a active only for EC fans] Function allows to ascribe particular speeds to particular gears of
ventilation. Given values [%] match the value of output voltage. The range of permissible values is 10% ÷ 100%. Nevertheless, one
has to remember that 0-10% value is considered as a STOP. So that the general range is bigger than that. During selecting
particular speeds, the controller automatically controls in the way that setting the gear with the bigger number has got bigger
percentage than previous one. The edition is the same as above.
•
mode 5 –
PRESOSTAT
If the recuperator is equipped with a pressure switch which measures the pressure drop
across the filters, the contacts can be connected to this input. This will provide a maximum information about usage
degree of filters.
•
mode 6 –
SPEED++ humidistat
It can be connected to WE5. After exceeding a certain value of humidity, the
controller will increase fan speed by one degree. If the humidistat continues giving a signal after about 20 minutes the
controller automatically will increase fan speed for the next step. This will remain until the signal disappears from
humidistat or if will remain max speed.
•
mode 7 –
Thermostat
protection against heater damage
