Specifications - Installation and Operating Instructions

The TSS2 is an electronic temperature controller designed for ON/OFF control or

Neutral Area Control. They can be provided with 1 or 2 probes (PTC or NTC)
according to parameter P5 and it provides 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:

Note: 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.

• Note: DO NOT INSTALL PROBE CABLE NEAR POWER CABLES.

Temperature of probe 1 >= SP2 -->relay 2 OFF

Mode ON OFF1 (On1) with r0=dep.

Output 1 works as in independent ON/OFF control (Figure 1 and 2), but output 2
works as follows:
Relay 2 with c2=dir.
Temperature of probe 1 >= SP1+SP2+r2 -->relay 2 ON
Temperature of probe 1 <= SP1+SP2 -->relay 2 OFF

Neutral Area Mode (nEU)

Relay 1

Operation in case of error.

If probe 1 fails, the operation is through c3. (See Parameter description.)
If probe 2 fails, the operation is through c4. (See Parameter description.)
In case of memory failure, both relays will remain open.
