OUT 4: Zone 4; „heating“ or „cooling“ „heating
Control output OUT 5: Zone 1; „cooling“

OUT 8: Zone 4; „cooling“
Alarm Output A1: Alarm 1 ( Temperature- or heater current monitoring alarm A1 for all zones)
Alarm Output A2: Alarm 2 ( Temperature- or heater current monitoring alarm A2 for all zones)
Setpoint Controlling: K1: open = Setpoint 1 (SP1) valid
K1: closed = Setpoint 2 (SP2) valid, for all zones
Adjustment lock (LOC): K2: open = Adjustment lock only via „software code“ (see parameter: LOC)
K2: closed = Adjustment locked according to the choosen „software code“.
Setpoint changing: K3: open = individual setpoint adjustment for each zone
K3: closed = if setpoint has been changed in one zone,
this new setpoint is valid (will be overtaken) for all other zones automatically.
CAN-Interface, (Option):K4: open = CAN: „operational“. Operation only with CANopen protocoll.
K4: closed = CAN: „operational“ always active.
K4 must be closed, if the instrument is equipped with a CAN-interface but not used.

Heater current monitoring: 1 current – transformer / phase
Single phase operation: terminals 76,77: L1
