Frequently Asked Questions - TS 2-1000 H-Tronic

What is the H-Tronic TS 2-1000?

The H-Tronic TS 2-1000 is a universal temperature switch (model TSM 2100) designed for precise temperature control in heating or cooling applications. It can be used as a thermometer, thermostat, frost guard, or with differential control for solar systems.

What sensors are required?

The device requires Pt1000 temperature sensors (not included). For modes using two sensors (modes 2, 4, 5, 6), a second Pt1000 is needed.

How do I set the switching temperature?

In the programming menu, use the ▲▼ buttons to adjust the ON (T1 EIN) and OFF (T1 AUS) temperatures in 1°C increments. Confirm with OK. The relay switches based on these values, with hysteresis depending on the mode (heating or cooling).

What are the available operating modes?

Seven modes: 1. Thermometer N1, 2. Thermometer N1 and N2, 3. Thermo switch N1, 4. Thermo switch N1 and N2, 5. Temperature difference (differential), 6. Circulation pump control, 7. Manual control. Also calibration and reset functions.

How do I set the alarm?

In the menu, set Alarm Min and Alarm Max temperatures. The alarm relay activates when the measured temperature goes outside this window. You can also set a delay (0-8 hrs) and choose whether the piezo beeper sounds.

What happens if a sensor fails?

The device detects sensor short-circuit or open-circuit and displays an error (Err 1, Err 2, Err 3). All relays switch off. You can predefine the relay state (ON, OFF, or unchanged) in the Relay status at malfunction setting.

Can I use the device for cooling?

Yes. The device automatically detects if it should operate as heating or cooling based on the ON and OFF temperatures. For cooling, set T1 EIN (ON) higher than T1 AUS (OFF). The relay then activates when temperature rises above the ON point and deactivates when it falls below the OFF point.

What is the maximum load?

The relays can switch a load up to 3000 W (16 A at 230 V/AC) total. For higher loads, use external contactors.

How do I calibrate the sensor?

Use the Sensor adjustment mode to enter offset corrections. R-Offset compensates for cable resistance (0-50 Ω), T-Offset adjusts the displayed temperature (-50°C to +50°C) for each sensor separately.

What maintenance is required?

The device is maintenance-free. Periodically check sensors for dirt or corrosion and clean gently. To clean the unit, disconnect from mains and use a soft, lint-free cloth. No other servicing is needed.

USER MANUAL TS 2-1000 H-Tronic

The unIVersal TemperaTure sWITch Tsm 2100 is ideal for all applications where a precise temperature control in heating or cooling is required. The unit can be used in the form of an independent monitor, as a frost guard, as a substitute for defective mechanical thermostats or as a digital thermometer. If the temperature ranges outside of the preset window, a relay will switch each channel individually after an adjustable time between 0-8 hrs. Another relay can also be connected to an alarm system. An internal beeper will also give an alarm signal if required.

The relay ALARM is switched ON if the measured temperature is higher or equal to T ALARM Max or lower or equal to T ALARM Min. The relay ALARM is switched OFF if the measured temperature is higher than T ALARM Min or lower than T ALARM Max.

8.1 FUNCTION MODE "HEATING"

The relay is switched OFF if the measured temperature is equal or higher than T OFF.

The relay is switched ON if the measured temperature is lower or equal to T EIN.

The relay ALARM is switched ON if the measured temperature is higher or equal to T ALARM Max or lower or equal to T ALARM Min.

8.2 FUNCTION MODE „COOLING“

The function "Cooling" is active if the programmed switching ON temperature is higher than the switching OFF temperature.

The relay is switched ON if the measured temperature is equal or higher than T EIN.

The relay is switched OFF if the measured temperature is lower or equal to T AUS.

The relay ALARM is switched ON if the measured temperature is higher or equal to T ALARM Max or lower or equal to T ALARM Min.

Note: if the programmed switching ON and switching OFF temperatures are identical then the device will execute the function "Thermometer". The relays REL and ALARM not switched.

An example for the functions "Heating" and "Cooling"

Example HEATING: you have a heating system which you would like to run as a temperature of 21°C with a hysteresis of +2°C. The input values would be as follows: switching ON value T1 EIN = 21°C and switching OFF value T1 AUS = 23°C. If the temperature reaches or drops beneath 21°C, the relay will switch the heating on. At 23° the relay will switch the heating off.

Example COOLING: you have a cooling system which you would like to run as a temperature of 21°C with a hysteresis of +2°C. The input values would be as follows: switching ON value T1 EIN = 23°C and switching OFF value T1 AUS = 21°C. If the temperature reaches or drops beneath 23 °C, the relay will switch the cooling on. At 21 °C the relay will switch the cooling off.
