9. HOTKEY

The configuration of the instrument can be done by serial RS485 line or thanks to the

HOTKEY DK00000100.

HOW TO COPY THE PARAMETERS FROM DEVICE TO HOTKEY

With device powered ON, insert the hotkey in the 5 pin receptacle, the device notices

the hotkey presence and the three LEDs flashes for three seconds in order to inform you

that the copy is starting. To indicate that the procedure ends up with success the

GREEN LED will blink for 5 seconds or otherwise if the procedure ends up without

success the RED LED will blink for 5 seconds, in this last case it's necessary to repeat

the procedure or to change the HOTKEY.

HOW TO COPY THE PARAMETERS FROM HOTKEY TO DEVICE

With device powered OFF, insert the hotkey in the 5 pin receptacle and switch on the

device. The procedure starts automatically and to indicate that the procedure ends up

with success the GREEN LED will blink for 5 seconds or otherwise if the procedure

ends up without success the RED LED will blink for 5 seconds.

10. ANTI-SWEAT HEATERS REGULATION (WITH RELAY

OUTPUT)

The default factory settings permit to regulate the anti-sweat heaters with the relay on

board and the external probe that should be placed on the glass. In case of the default

parameters aren't able to give you the optimum performance, we can advise to change

the following parameters:

1592030000 xh50_55p r1.2 gb 2011.06.28.doc

Descrizione

Range

odr

Regulation offset

[-12.0 ÷ 12.0°C] [-21 ÷ 21°F]

Regulation differential

[0.1 ÷ 25.5°C] [1 ÷ 45°F]

tAr

PWM period

10 ÷ 255 min

The odr parameter is setted at 1.0°C by default and permits a small safety margin

during the regulation. The Hy parameter permits to set the modulation band for the

power of the heaters. Reducing Hy the load stays OFF for more time (at the same

temperature and dew-point), increasing Hy we can obtain the opposite functioning. The

relay commutation is performed on the tAr time.

11. ANTI-SWEAT HEATERS REGULATION (WITH ANALOG

OUTPUT)

The regulation of the anti-sweat heaters through analog output is obtained by changing

AOC parameter to dEP value. After that, it's possible to refine the regulation using odr

and Hy parameters.

12. CONFIGURATION AS THERMOSTAT

By setting rLC=tER the relay works as a simple thermostat based on set point. In this

case, the device works as zone thermostat in heating mode. By changing the parameter

it's possible to invert the action.

13. KNOB (ONLY XH55P)

In case of XH55P it's present a knob that permits to set an offset respect to the set

point of 3°C (this value can be changed with Ltr and Utr parameters). If the knob is

completely turned off all the output are switched off.

14. PARAMETER LIST

Set

Regulation set point: is the set point for relay or analog output regulation.

Regulation differential: band for the regulation of the relay or histeresys of

activation/deactivation of relay during thermostatic functioning.

odr

Regulation offset: offset for regulation set point.

HES Energy saving offset: is the energy saving offset that is added to the set point

when the digital input configured as i1F=ES is activated.

XH50-55P

Regulation kind of action: direct or reverse functioning for the relay.

Default

rPA

Regulation probe A: selects the first regulation probe between: nP=not

1.0°C

present, external probe (Etr) or internal probe (int).

5.0°C

rPb

Regulation probe B: selects the second regulation probe between: nP=not

10 min

present, external probe (Etr) or internal probe (int).

rPE

Regulation percentage between probes A and B: percentage between probe

A and probe B. The virtual probe follow the formula:

Value = (rPA*rPE + rPb*(100-rPE))/100

Measurement units: °C=Celsius; °F=Fahrenheit. WARNING: after changing

measurement unit you have to check all the values of all parameters.

odS

Start up outputs delay: allows starting the output and the regulation with soma

delay to allow measurement stabilization.

rHC

Digital humidity sensor presence: enable or disable the humidity sensor.

orH

Humidity sensor offset: it permits simple reading offset.

tdC

Digital temperature sensor activation.

Digital temperature sensor offset: it permits simple reading offset.

AuC External temperature sensor presence: it permits to enable/disable external

probe.

External temperature sensor offset: it permits simple reading offset for

auxiliary probe.

AOC Analog Output working mode: select the working mode for analog output.

If:

nP: not present, analog output deactivated.

Etr: analog output regulation based on the external temperature probe.

int: analog output regulation based on the internal temperature probe.

HPr: analog output regulation based on the humidity value.

dP: analog output regulation based on the dew-point temperature.

dEP: analog output regulation based on the dew-point.

MAn: analog output goes on An value.

The value of analog output can change from 0 to 100% inside of the band define

by LAO and UAO as reported on the following charts.

--------- --------- --------- --------- --------- --------- ---------

AoC=Etr, int, HPr, dP and Ant=dir
