Specifications - Installation and Operating Instructions

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

eutral Area Control. They can be provided with 1 or 2 probes (PTC or NTC)

ccording to parameter P5 and it provides two output relays plus an alarm buzzer.

a 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:

Parameter descriptions SP1 = Operation order of relay 1. Specifies the ON/OFF point of relay 1. Variable

between r4 and r6. SP2 = Operation order of relay 2. Specifies the ON/OFF point of relay 2. Variable between r5 and r7. r0 = Dependency between SP1 and SP2. Only for mode ONOFF1 ind = order for relay 2, SP2. dep = order for relay 2, SP1+SP2. r1 = Differential or hysteresis for relay 1. Temperature differential between ON/OFF of relay 1 in ON/OFF control. r2 = Differential or hysteresis for relay 2. Temperature differential between ON/OFF of relay 2 in ON/OFF control. r3 = Band differential. Temperature differential between ON/OFF of relays 1 and 2 in neutral area control. For relay 1 it is added to SP1 and for relay 2 it is subtracted from SP1.

r4 = Lowest value for SP1. r5 = Lowest value for SP2. r6 = Highest value for SP1. r7 = Highest value for SP2. r8 = Regulation or operating mode. Selection of the operating mode. A0 = Alarm differential. It is the temperature differential between the alarm On and

Off cycle.

A1 = Maximum alarm probe1. A2 = Maximum alarm probe2.

A3 = Minimum alarm probe1.
