Love Controls TSS2 series User manual

The TSS2 is an electronic temperature controller designed for ON/O
control or Neutral Area Control. They can be provided with 1 or 2 probes
(both PTC range -58 to 302º ) according to parameter P5 and it
provides with two output relays plus an alarm buzzer. The unit controls
cooling, heating or both, since its relays can be setup for direct or
reverse operation. The user is able to program 34 different parameters
including set points, hysteresis, configuration of alarms and probe
adjustment using the silicone front keypad. The unit features error
warning and password protection.
Each suffix can take the following values:
OTE: Unit must be mounted away from vibration, impacts, water and
corrosive gases.
• Cut hole in panel 71 x 29 mm (2.80 x 1.14 inches).
• Apply silicone (or rubber gasket) around the perimeter of the hole to
prevent leakage.
• Insert unit into hole of panel.
• Slide removable fitting clips onto unit from the back until secure to
panel.
• Wiring diagram is displayed on the top of the unit.
• ote: DO NOT INSTALL PROBE CABLE NEAR POWER CABLES.
