Manual Storage Heater TTS with electronic control
GB
Plug assignment
❍
Supply voltage of the charge regulator
(230 V AC) - Stecker L und N
❍
Control of thermocouple (230V AC)
Plug TRL and TRN
❍
Control voltage 230 V AC (Z1 - Z2 for weather-dependent charging)
Plug A1 and A
Installation of the charger
When installing the charger, care must be taken that the clearance and creepage distances of 8
mm are maintained.
❍
Connection of the supply voltage
The charger can be connected either to the high-tariff circuit or to the low-tar circuit. The controller is
functional for both connection variants
Charging of the storage heater
The charge controller has 2 LED indicators: one green to indicate the operating state, and one red to
indicate the fault. After the supply voltage is switched on, the green LED flashes: the controller is ready
for operation. After release - during charging, the green LED is lit continuously - the thermocouple is
switched on.
Response times of a few seconds must be observed.
Disturbances
Sensor break:
When the sensor is broken, both LEDs flash, no charging occurs.
Sensor Short Circuit: The charger can not detect a short-circuit of the sensor. If this is the case, the
green LED is lit continuously and the heat accumulator is charged up to the max.
Off temperature of the safety limiter.
Note:
If necessary, the customer service can determine the zero voltage at the
thermocouple in the two cases using an mV analogue or digital measuring device
(only with a warm device, otherwise 0mV)
If the setpoint core temperature is exceeded by 100 K, the red LED is continuously lit. The green LED
flashes. The charging process is interrupted, but the charge continues until the core temperature falls
below its setpoint.
Setpoint generator:
If the connection to P1 is missing, the green LED flashes and there is no charge.
If the P2 is not connected, the green LED flashes and there is no charge; If the
connection to the P3 is missing - the green LED is lit and the heat accumulator
charges up to the max. Adjusted core temperature from the charger;
With missing potentiometer
The green LED flashes and there is no charge instead.
If the core probe is incorrectly connected and the heat storage unit (potentiometer on) is switched on,
the green LED is continuously on, and the heat accumulator is charged until the safety limiter is switched
off.
Always interrupt all electrical circuits before undertaking any work in the electrical compartment.
