The TS Digital Temperature Switch is designed for many
heating and cooling applications. The probe temperature is
displayed on the bright 3-digit, red LED. The user is able to
program 12 different parameters including set point,
hysteresis, cycle time, and ambient probe adjustment using
the front keypad. The unit features error or alarm messaging
and password protection. Select between temperature
display in °F or °C, and 110 VAC, 230 VAC, or 12 VDC
power supplies. The TS includes a thermistor with 5 ft (1.5
m) cable, fitting clips for panel mounting, and instruction
manual.
INSTALLATION
NOTE: Unit must be mounted away from vibration,
impacts, water and corrosive gases.
• Cut hole in panel 2.80 x 1.14 inches (71 x 29 mm).
• Apply silicone (or rubber gasket) around the perimeter of
the hole to prevent leakage.
• Insert unit into hole in the panel.
• Slide removable fitting clips onto unit from the back until
secure to panel.
• Remove back cover to wire unit.
• Wiring diagram is displayed on the top of the unit.
• (Note: PROBE CABLE LENGTH MUST NOT EXCEED
328 ft (100 m). DO NOT INSTALL PROBE CABLE NEAR
POWER CABLES).
• Replace cover once wiring is completed.

Access to all code protected parameters.
PARAMETER DESCRIPTIONS
SP = Set Point - Desired Regulation Temperature.
r0 = Differential or Hysteresis.
r1 = Lower Set Point Limit.
• Press SET for 8 seconds. The access code value
00 is shown on the display. (Unit comes with
code set at 00 from factory).
r2 = Higher Set Point Limit.
• With the UP and DOWN arrows, code can be set to
user needs.
d0 = Heating or Cooling Control - This control only does
regulation cycles. Neither defrosting nor continuous
cycles exist.
• Press SET to enter the code. If it is correct, the first
parameter label is shown on the display (SP).
Heating: To choose Heating Control - Set d0=Ht
(The output is activated when TS1 [temperature of
ambient probe] is less than or equal to Set Point.)
TS1<=SP. It then disconnects when TS1>=SP-r0.
Cooling: To choose Cooling Control - Set d0=Co
(The output is activated when TS1>=SP+r0.) The
display will switch off when TS1<=Set.
d2 = Duration of Defrosting Time (The value
programmed from the factory is d2=15 minutes.
[Ht-defrosting will never start, if Co=0, defrosting
will never start.])
d8 = Interval time between defrosting.
• Move to the desired parameter with the UP and
DOWN keys.
• Press SET to view the value on the display.
• The value can be modified with the UP and DOWN
arrows.
• Press SET to enter the value and exit to test
parameter.
• Press SET and DOWN at the same time to quit
programming or wait one minute and the display will
automatically exit programming mode.
LED INDICATIONS
c0 = Minimum time between start and stop.
c1 = Continuous cycle time.
P1 = Ambient Probe Calibration. (Offset degrees to
adjust ambient probe. If the probe is not placed in
the exact point that is to be measured, use a
standard thermometer and adjust the difference in
this parameter.)
H5 = Access to probe parameters. (This code is set to
00 from the factory.)
t0 = Maximum temperature on display. (Temperature
limit for defrosting.)
OUT This indicates the load is connected. The
system waits for the programmed minimum
stop time of the load.
Def
This indicates defrosting is activated.
DISPLAY MESSAGES
In normal operation, the probe temperature will be shown
on the display. In case of alarm or error, the following
messages will be shown:
• ER = Memory Error
• -- = Short-Circuit Probe Error
• oo = Open Probe Error
PARAMETER PROGRAMMING
Access set point (SP) without code protection.
MAINTENANCE/REPAIR
• Press SET. SP text will appear on the display.
After final installation of the TS Series Digital Temperature
Switch, no routine maintenance is required. A periodic
check of system calibration is recommended. These
devices are not field repairable and should be returned to
the factory if recalibration or other service is required. After
first obtaining 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.
• Press SET again. The real value is shown on the
display.
• The value can be modified with the UP and DOWN
arrows.
• Press SET to enter any new values.
• Press SET and DOWN at the same time to quit
programming or wait one minute and the display
will automatically exit programming mode.
