H : Auxiliary control: input probe that acts as an independent variable, set point, minimum and maximum output
limits, PID parameters, type of control in cooling/heating - direct or reverse.
W :
a. Input/output status For each logical input/output value, the following can be displayed: analogue input:
– the input that the current measurement and value are associated with;
– digital input: the input that the measurement, logical value, activation logic and hardware value are associated with;
– analogue output: the output that the current measurement and value are associated with;
– digital output: the output that the measurement, logical value, activation logic and hardware value are associated with.
b. Confi guration. For each physical input/output, the following can be set/displayed (for the settings, see “Commissioning”):
– universal inputs: the board and channel, the type, the description of the associated measurement, the value/status, any
confi guration errors, any minimum and maximum output limits, off set and fi lter (depending on the type);
– digital input: the board and channel, the description of the associated measurement, the status, any confi guration errors;
– analogue output: the board and channel, the type, the description of the associated measurement, the value, any con-
fi guration errors, minimum and maximum output limits, any off set and fi lter; digital output: the board and channel, the
description of the associated measurement, the status, any confi guration errors;
Y : Connectivity: serial port communication parameters
;
Z : Exit programming level and login again with diff erent user level (with password).
7.3 Manufacturer parameters
The manufacturer (password 5678) can access all of the read/write parameters. The manufacturer can:
• select the devices, the device opening values in the event of a control probe error, activate the frost protection function both
during operation and when OFF, enable auxiliary control, the heating coil, cooling coil and electric heater;
• enable and confi gure the th-Tune terminal;
• enable the devices on the unit: return fan, heat recovery unit, humidifi er, type of fans;
• enable and confi gure warm-up at power on;
• enable and confi gure frost protection and frost prevention (low supply temperature);
• select the unit operating mode in the event of a control probe error: (force the unit OFF/activate devices at a fi xed %, Ac16);
• select the possible operating modes based on the devices on the unit; set the air pressure/fl ow-rate conversion coeffi
cient K;
select the type of fans, heating device (heater/water coil) and the type (ON/OFF, modulating);
• select the type of heat exchanger (plate/rotary), outside air damper and bypass damper;
• select the type of humidifi er (modulating/humiSonic/Humifog).
