Remember that the display on the probe can be modified by the
display lock function with parameter defrosting. "D.dL" (see
function. "Defrost").
4.3 – THERMOSTAT TEMPERATURE
The mode of regulation of the instrument is the ON / OFF type on
the relay outputs depending on the probe and the active Set Point
"SP" and the differential (hysteresis) intervention "rd" and mode
"r.HC".
In the operation mode set in the "r.HC" parameter applies to the
following differential: ("r.HC" = C) setting cold (cold) the differential
used as positive and triggers the relay to reach the set point and
stops again until the temperature exceeds the set point +
differential. If ("r.HC" = H) configuration Heat (Heat) the differential
used as negative and triggers the relay to reach the set point and
stops until the temperature drops again below the set point -
differential.
In case of probe error is possible that the output programmed as
function ot cycling time programmed on par. "R.t1" (activation time)
and "r.t2" (deactivation time) for error.
Programming "t1" = oF the output probe condition remains always
off.
Programming "r.t1" any value "r.t2" = oF the output in probe error
condition will remains On.
It is recalled that the operation temperature can be conditioned on
the following functions:
"Compressor Protection", "Delay-start" and "Defrost".
4.4 – COMPRESSOR PROTECTION
Compressor protection feature helps to avoid very frequent
compressor starts or it can also be useful for control in time for the
relay output to an actuator or intended load. Activate this function
provides 3 types of timing choice as appropriate to the control
system.
The protection is to prevent multiple starts during the time of
protection.
The first provides a delay time to the activation of the output
according to the time set in the "P.P1" parameter (delay to start).
The second time provides a delay of control relay, in order to
ensure a minimum time between the arrest and the progress of the
relay parameter: "P.P2" (delay after stop or minimum downtime).
The third time provides permit no starts if has exceeded the
programmed time between consecutive starts. Parameter "P.P3"
(delay after consecutive starts).
If protection is acting, hindering the progress of the relay for the
programmed time, the relay output LED (Cool or Heat) is flashing.
Is possible activate a delay to the start of the regulation to when
arrives the supply to the thermostat. Parameter "P.od" very suitable
when multiple thermostats to not start at the same time allowing the
loads and power line a softer boot.
During this phase delay visualize od alternating scheduled to
normal viewing.
The delay function "od" = disables programming as oF.
4.5 – DEFROST CONTROL
The defrost timer is type "compressor failure" at scheduled
intervals.
Defrost is programmed in the parameter "D.Di" time between
defrost cycles between the end of one and beginning of the
successive. We can force a defrost at first start defrost, par.
"D.Sd".
If you want each instrument start defrosting is done schedule time
parameter "d.Sd" = oF. So starting immediately conduct one.
If you do not want to start defrosting then will the defrost cycle for
this program "d.Sd" = "D.Di".
Programming "D.Di" = oF all defrosting is disabled. Therefore, the
instrument provides each defrost, compressor disable relay for the
time "d.dE".
4.5.1 – MANUAL DEFROST
To activate a manual defrost press the "Up / DEFROST" button for
5 seconds and the led "Def" lights and perform defrosting. To
terminate a defrost cycle while doing this press the "Up / Def"
button again for 5 seconds.
4.5.2 – LOCK DISPLAY DURING DEFROST
Using parameters "d.dL" and "A.Da" display behaviour is
established during defrosting.
The "d.dL" parameter causes blockage of the last temperature
before defrost on the display ("d.dL" = on) until you reach the end
of defrost and the temperature does not exceed below the value of
the last preset temperature or condition ["SP" + "rd"], or times out
lock security. "A.Da".
Also allows visualization of the indicative initials Defrost "dEF" ("dl"
= Lb) and after defrost the acronym "PdF" indicating time defrost
finish temperature cold but not recovered to control value ("SP" +
"rd") or times out lock security. "A.Da".
Another possibility is to indicate the actual temperature of the cold
chamber or cabinet, during defrosting ("d.dL" = oF).
4.6 - ALARM FUNCTIONS
Alarm conditions:
- Probe Error: "E1", "-E1"
- Temperature alarm: "Hi", "Lo"
The alarm function is displayed in LED and ALARM programmable
internal buzzer in the "o.bu" parameter.
The pair. "O.bu" allows the configuration of the internal buzzer:
= OF - off buzzer
= 1 - the buzzer is activated only for alarm signals
= 2 - the buzzer is activated only to point out the key presses and
no warning signs.
= 3 - The buzzer is activated only to point out the keystrokes and
alarm signals.
