PROBES (Pr0)
P0 = Temperature scale. Select between °F and °C.
P1 = Primary probe calibration. Degrees shift of the primary probe display value.
P2 = Defrost probe calibration. Degrees shift of the defrosting probe display value.
P3 = Product probe calibration. Degrees shift of the product probe display value.
P4 = Decimal point
P5 = Probe to display. Probe to be viewed normally on the display.
P6 = Probe 2 present. If there is a probe 2 connected to thermostat.
P7 = Probe 3 present. If there is a probe 3 connected to thermostat.
ALARMS (ALA)
A0 = Fan & alarm differential.
This is the temperature difference between the on and off cycle of the alarms and fan.
A1 = Maximum alarm. High alarm ON at Set+A1. High alarm OFF at Set+A1-A0.
A2 = Minimum alarm. Low alarm ON at Set-A2. Low alarm OFF at Set-A2+A0.
A3 = Time validation open door or external alarm. If open door or external
alarm is maintained during this time, alarm will be indicated. (Depending on the E0
configuration of digital input).
A4 = Alarm exclusion time after defrosting. During the defrosting and this time after
it, temperature alarms will be ignored.
A5 = Alarm exclusion time after opening the door. While the door is open (if A5>0)
and time A5 after closing it, alarms will be ignored.
A6 = Alarm exclusion after connection. Until this time has elapsed since the
connection, temperature alarms will be ignored.
A7 = Temperature alarm time validation. Time since the alarm situation occurs, until
it is given.
A8 = Probe Alarm.
sd1 = primary probe
sd2 = defrosting probe
sd3 = product probe

INITIALIZATION (Ini)
Hor = Hour
Min = Minutes
E0 = Digital input configuration.
Off = Digital input disabled.
Al = External alarm. There is an alarm if input is short-circuited.
In = Door open if input is short-circuited.
def = Order to initiate a defrost if input is short-circuited.
ndf = No defrosting will be made if input is short-circuited.
H0 = Factory Configuration. Record Factory Configuration.
H1 = Master/Slave
H1 = Master. The thermostat issues defrosting orders to slave connected thermostats
through the digital input.
H1 = Slave. The thermostat performs defrosting ordered by the master connected to
its digital input.
In both cases the input must be E0=def.
H2 = Keyboard protection.
Yes = Keyboard protected. To modify Set, activate/de-activate defrosting and
activate/de-activate continuous cycle we have to enter the code and then quit. The
protection is removed momentarily. It is activated again 1 minute after the last key is
pressed.
No = Keyboard not protected.
H3 = Delay time on connecting. Until this time has elapsed since turning-on power,
the compressor will not start-up.
H5 = Input code to parameters. This code is set to 0 from factory.
H6 = Type of Probe. PTC or NTC.
H7 = Configuration Relay 2.
H8 = Configuration Relay 3. We can choose that it is light (Li), fan (Fan), alarm (ALA),
defrosting (dEF), or reverse fan (FAI).
H10 = HAACP activated. Yes or no.
HdE = Hours (HdE) portion of the time the defrost will begin at.
MdE = Minutes (MdE) portion of the time the defrost will begin at.
HACCP (HAC): (Only appears when H10 is set to yes).
nAt = # of recorded alarms.
Adx = Temperature of alarm point where x can be 1 through 5.
tdx = Time of alarm point where x can be 1 through 5.
dxx = days
hxx = hours
nxx = minutes
MAINTENANCE/REPAIR
Upon final installation of the Series TSXT no routine maintenance is required. The
Series TSXT is not field serviceable and should be returned if repair is needed. Field
repair should not be attempted and may void warranty.
CLEANING & REPAIR
Clean the surface of the display controller with a soft, damp cloth. Never use abrasive
