POLA HP57 - Thermo-Hygrostat Controller Handbook Manual

MAIN SETTINGS

TEMPERATURE SETTING

Press TEMP key (key lamp flashes):

This message will be displayed instead of the °C Set Temperature value.

Press + or - to modify. Press TEMP to confirm.

Example with SEt.t = 20.0°

HUMIDITY SETTING

Press HUM key (key lamp flashes):

This message will be displayed instead of the % Rh Humidity value.

Press + or - to modify. Press HUM to confirm.

Example with SEt. H = 80.0H

VIEWING TEMPERATURE AND HUMIDITY

With TEMP key lamp light (press TEMP key) ambient temperature is displayed. With HUM key lamp light (press HUM) ambient humidity is displayed (if the humidity is obtained with "wet bulb" pressing HUM for more than 3 second on display will appear the message t.vEt in turn of obtained value of temperature probe "wet bulb").

VIEWING AMBIENT TEMPERATURE AND AMBIENT HUMIDITY RECORDING

TEMPERATURE RECORDING VIEWING

Press TEMP key and after:
TEMPERATURE RECORDING VIEWING

HUMIDITY RECORDING VIEWING

Press HUM key and after:
HUMIDITY RECORDING VIEWING

Values recorder are memory permanent stored: for memory clear keep pushed + keys for more than 3 seconds: CLEA message will be composed on display before clearing operation.

COSt PROGRAMMING (System constants)

These settings refer to the operation mode of the system and must be made on initial startup. Press - / + at the same time for at least one second: the message C.O.S.t. will be displayed.

Press than repeatedly HUM until the message regarding the chosen variable is displayed (see table below): value of variable and message will be displayed.

Press + or - to set a new value and then press HUM to confirm.

The next system constant will then appear.

You can press HUM for at least 2 seconds to exit and return to the Run Mode.

Mess.	Value	Meaning	Note
*diF.t*	0.2 °	° temperature differential	*1)
*rEL.t*	0.0 °	° setting shift referring to *Set.t*	*1)
*CYC.t*	0"	Temperature regulation cycle time in seconds	*1)
*min.t*	0"	Minimum time temperature activating cycle in seconds	*1)
*diF.H*	1.0%	° Humidity differential	*1)
*rEL.H*	0.0%	%Rh setting shift referring to *Set. H*	*1)
*CYC.H*	0"	Humidity regulation cycle time in seconds	*1)
*min. H*	0"	Minimum time humidity activating cycle in seconds	*1)
*tEnP*	=1	Temperature representation (=1°C, =2°F)
*Huny*	=0	Humidity sensor type (0= psychometric, 1= 4-20mA)	*2)
*Ad.tE*	0.0 °	° Input temperature sensor correction (+ or -)	*3)
*Ad.tu*	0.0 °	° Input temperature wet bulb sensor correction (+ or -)	*4)
*Ad. Hu*	0.0%	%Rh Input humidity correction (+ or -)	*5)

*1) For more details see Operating Diagram.

*2) See also Installation.

*3) You can correct the readings on the temperature sensor (+ or -).

*4) You can correct the readings on the wet bulb probe sensor (+ or -).

To calibrate the %RH reading (when using the psychometric kit):

Remove the wet sock from the wet temperature probe.
Allow the wet temperature probe to dry for 10 mins.
Adjust the above setting to make the wet bulb temperature match that of the dry bulb. Check periodically the sock installed on the sensor has not been clogged by calcium carbonate scale. If you, remove it and clean or replace it.

*5) You can correct the readings on the 4-20mA humidity sensor (+ or -).

PRESET PROGRAMS (Bootstrap)

This processor is already programmed with the following (variable) settings.

To return to these settings at any time you may:

Power off the processor, press HUM key and keep it pressed giving power on: boot message will be displayed (release now HUM key).

SEt.t=20.0° SEt. H=80.0H.

The COSt values are shown in COSt Programming.

"HAND" MODE

In some start-up conditions may be useful to work in "manual" mode:

Power off the processor, press + key and keep it pressed giving power on: HAnd message will be displayed (release now + key). Push + until is displayed number required to be handed (see table State indication lamps) and push HUM for activating relay. Pushing again + for increase relay number previous relay is deactivated.

You can press HUM key for a least two seconds to escape and return to the Run Mode.

STATE INDICATION LAMPS

Lamp.	State	N° Relay	Contacts
HEAT	Heat On	1	3-4
COOL	Cool On	1	4-5
HUM	Hum On	2	6-7
DEHM	Dehm On	2	7-8

OPERATIVE DIAGRAMS

TEMPERATURE

* In the case of proportional working (CYC.t different from 0") we suggest to set:
diF.t = 2.0°CYC.t= = 120" min.t= = 5"

HUMIDITY

INSTALLATION

How to connect the sensors

To connect the 2 probes use N.2 two-wire cable 0,5 mm2 section, taking great care over the connections, by insulating and sealing the joins carefully. -O.C.- is displayed when the temperature sensor wiring is open, -S.C.- is displayed when the temperature sensor wiring is short circuit.

How to connect the line

Connect line on terminals L-N. Protect supply with adequate fuse.

How to connect the contacts

Connect terminals on the terminal block (contacts up to 4AMP.AC1).

*1 Other power voltage if you required.

*2 How to connect humidity-psychrometer system (wet bulb).

WT1 Option.

Psychrometric kit with predisposition to fixing ambient probe (SX air) and wet probe (SXPS water). Water tank with transparent side to check the water level and plug for water inlet.

In the case of our WT1 option (water tank) will not used, deep only the terminal side of the wetting cover of SXPS probe.
Put SX probe (dry bulb) in the closeness.
WT1 Option

Check periodically the sock installed on the sensor has not been clogged by calcium carbonate scale. If so, remove it then clean or replace it.

*2 How to connect 4-20mA electronic humidity probe.
