DESCRIPTION

Monitor and control temperature for heating and cooling applications with

the Series TS2 Digital Temperature Switch. The Series TS2 offers twelve

programmable functions to customize the unit to fit application require-

ments. Use the 15(5) Amp SPDT relay output to drive a motor, compres-

sor, or fan. Designed with the OEM in mind, the TS2 offers the ability to

configure multiple units with the touch of a button.

Programming multiple units is quick and easy. Simply program one switch

with the desired parameter settings and connect the configuration key

(sold separately) to the back of the unit. Press the button on the configu-

ration key and download the parameter settings. Connect the key to the

other switches to upload the stored settings with the push of a button.

The TS2 features set point adjustments, static defrost timing, compressor

mean time, hysteresis, and ambient probe adjustment. Security protec-

tion is offered using a password code. The Series TS2 Digital

Temperature Switches are designed to operate with PTC (1000Ω @

25°C) probes sold separately.

INSTALLATION

The thermostat must be installed by authorized professionals. It should

be located in a place free of vibrations, impacts, water and corrosive

gases.

A hole measuring 71 x 29 mm must be cut in the panel where the ther-

mostat is to be fitted (apply silicone to make it leaktight). Then, the fixing

cups must be fitted, sliding them onto the thermostat until secure. Do not

force tightening of the screw if the U-brackets are used. The connections

must be covered with the rear cover for this.

WIRING INSTRUCTIONS

Avoid installing the probe’s cables in proximity with any power cable. If

the length of the probe cables measures more than 100 meters, a recali-

bration adjustment must be made (parameter P1).

FRONT OPERATION

PUSH BUTTONS

Pushing SET once gives access to the SP. Pushing for 8 sec-

onds gives way to the requested code. After entering the cor-

rect code, all parameters are accessible. This button alternates

between text parameters and their value. It validates the modi-

fied parameters. When pressed with DOWN, it exits parameter

programming.

Pressing this arrow allows the user to go to the next parameter

or increase the value viewed on the display. When pressed for

8 seconds, it activates or deactivates defrosting.

Pressing this arrow allows the user to go to the previous param-

eter or decreases the value viewed on the display. When

pressed for 8 seconds, it activates or deactivates the continuous

cooling cycle. When pressed simultaneously with SET, it exits

the programming mode.

PROGRAMMING PARAMETERS

Access only to Set Point SP (without code protection):

•Press and release SET. SP text appears on the display.

•Press SET again. The real value is shown on the display.

•Modify the value using the UP and DOWN keys.

•Press SET and DOWN to quit programming, or wait 1 minute for the

TIMEOUT.

Access to all parameters (code protected):

•Press SET for 8 seconds. The access code value 00 is shown on the dis-

play.

•Using the UP and DOWN buttons, set the code (factory-set code is 00).

•Press SET to enter the code. If it is correct, the first parameter label will

be shown on the display (SP).

•Move to the desired parameter with the UP and DOWN keys.

•Press SET to see the value.

•Modify the value with the UP and DOWN keys.

•Press SET to enter it, and exit to text parameter.

•Press SET and DOWN to quit programming, or wait 1 minute for the

TIMEOUT.

SETTING THE KEYBOARD CODE TO ZERO

The keyboard code can be set to zero by holding the SET key and turn-

ing the controller off then on again.

LED INDICATIONS

Out: This indicates that the compressor is connected. It waits the pro-

grammed minimum stop time of the compressor.

Def: This indicates that defrosting is activated.

MESSAGES DISPLAY

In normal operation, the probe temperature will be shown. In case of

alarm or error, the following messages will be shown:

• Er- Memory error.

• -- Short-circuited probe error.

• oo- Open probe error.

PARAMETERS

PARAMETER DESCRIPTIONS

SP = Set Point. Temperature wished to regulate the machine. Can vary

from r1 to r2.

r0 = Differential. Heating: If temperature is ≥ Set then out OFF. If tem-

perature is ≤ Set then out OFF. Cooling: if temperature is > Set + r0 then

out ON. If temperature is ≤ Set then out OFF.

r1 = Lower Set Point Limit

r2 = Higher Set Point Limit

d0 = Heat or Cooling Control. Ht = heating control, Co = cooling con-

trol.

d2 = Defrosting Time Remaining, in minutes. If d2 = 0, defrosting will

not start.

d8 = Interval Between Two Defrostings, in hours.

c0 = Minimum time for compressor to be OFF. Minimum time from

when the compressor stops till it connects again.

c1 = Continuous Cycle Time. The remaining time for a continuous cold

cycle.

c2 = ON time of fault cycle, during probe error.

c3 = OFF time of fault cycle, during probe error.

P1 = Ambient Probe Calibration. Offsets degrees to adjust the ambient

probe.

H5 = Access Code to Parameters. Factory-set as 00.

t0 = Temperature Display Limit. Maximum temperature shown on the

display, although the real temperature can be greater.

OPERATION IN CASE OF ERROR

If the probe or thermostat memory should fail, the compressor will be con-

nected for 5 minutes ON then 5 minutes OFF.

MAINTENANCE

CLEANING

Clean the surface of the display controller with a soft, damp cloth. Never

use abrasive detergents, petrol, alcohol or solvents.

REPAIRS

After final installation of the TS Series Digital Temperature Switch, no rou-

tine maintenance is required. A periodic check of system calibration is rec-

ommended. The devices are not field repairable and should be returned

to the factory if recalibration or other service is required. After first obtain-

ing a Returned Goods Authorization (RGA) number, send the material,

freight prepaid, to the following address. Please include a clear

description of the problem plus any application information

available.
