Low values assigned to this parameter allow a prompt response ofthe sensor to temperature variations, but the reading becomes more sensitive to disturbance. High values slow down the response, butguarantee greater immunity to disturbance, that is, a more stable and more precise reading. The parameter acts on the temperaturereadings, fi ltering the minimum variations, and at the same time considers the average of the readings. Default: ‘/2’=4./3: Probe display responseThis parameter is used to set the update rate for the temperature display. The temperature shown on the display tends to follow rapiddeviations away from the set point very slowly, and vice-versa, moves very quickly in the event where the temperature displayed isnearing the set point. If the control temperature exceeds the high or low temperature thresholds (and an AL or AH alarm is activated), orif the maximum number of fi ltering steps (255) is exceeded (see the Timeout column in Table 7.b), the fi ltering would immediately bebypassed and the temperature displayed would be the temperature eff ectively measured, until all the alarms are reset. The parameteronly aff ects the temperature displayed, and not the temperature used for the control functions.Important:• the control temperature actually measured diff ers from the value displayed, and therefore the outputs may not be activated withreference to the latter temperature value.• if the probe displayed is a product probe, with temperature values higher than the set point, the probe display rate algorithm willbe faster for decreases in the temperature and slower for increases;• if the probe displayed is an evaporator or condenser probe, the display rate algorithm always refers to the set point and thus mayhave specifi c eff ects (fast when the evap. probe reading increases and slow when it decreases; fast when the condenser probereading decreases and slow when it increases);• the parameter /3 acts on the temperature displayed by the instrument, if /tE=0 (no probe displayed by the repeater display); ifthe repeater display is confi gured (/tE <> 0), the parameter /3 will act on the temperature displayed by the repeater.Example: in the case of “bottle coolers”, typically used in supermarkets, when the doors are opened frequently, due to the greaterthermal inertia of the liquids compared to the air (and the fact that the probe is positioned in the air and not directly on the products),the instrument measures a temperature that is higher than eff ective temperature of the soft drinks, thus displaying a quite“unrealistic”temperature. Setting the parameter /3 to a value other than 0, any abrupt variations in temperature are “fi ltered” on the display,showing a temperature trend that is “closer” to the actual trend of the product temperature. The following table shows the possiblevalues of ‘/3’ and the corresponding display delayed update values (Tdel).Value of par. /3 Display delay (Tdel) Timeout0 Disabled 01 5 s 21 min2 10 s 42 min3 15 s 64 min4 20 s 85 min5 25 s 106 min6 30 s 127 min7 40 s 170 min8 50 s 212 min9 60 s 255 min10 75 s 319 min11 90 s 382 min12 105 s 446 min13 120 s 510 min14 150 s 637 min15 180 s 765 minTab. 7.bDefault: ‘/3’=0 => Function disabled./4: Probe average (virtual probe)This parameter is used to choose whether to control the temperature based solely on the room probe reading, or alternativelywhether to refer to the “weighted” average of the room probe S1 and probe 2 (S2, see the parameter ‘/A2’). This parameter isuseful in special applications.7. DESCRIPTION OF THE OPERATING PARAMETERS |
