Abstract: A control device includes first and second control modules. The first control module is configured to generate process data at t1, send the process data to the second control module via a communication channel, receive a response to the process data, and process the process data at t4. The second control module is configured to receive the process data from the first control module, process the process data at t2, generate the response at t3, and send the response to the first control module. The times t1, t2, t3, and t4 are in chronological order. In various implementations, the first and second control modules jointly guarantee a minimum duration ?1 between t1 and t2. In various implementations, the second control module guarantees a minimum duration ?2 between t2 and t3. In various implementations, the first and second control modules jointly guarantee a minimum duration ?3 between t3 and t4.

Abstract: A measuring arrangement comprising a heat meter having a flow sensor, a first temperature sensor, a second temperature sensor and computing means. The first temperature sensor serves to register a temperature in the feed line of the heat exchanger and the second temperature sensor serves to register a temperature in the drain line of the heat exchanger. The computing means serves to calculate the amount of heat exchanged. A first transfer function, which serves to determine the temperature in the feed line based on a measurement signal of the first temperature sensor, is stored in the computing means; a second transfer function is stored in the computing means; wherein the first transfer function differs from the second transfer function; and the second transfer function serves to determine the temperature in the drain line based on a measurement signal of the second temperature sensor.

Abstract: A measuring arrangement comprising a heat meter having a flow sensor, a first temperature sensor, a second temperature sensor and computing means. The flow sensor serves to register volume or mass of a heat transport medium flowing in the feed line or drain line of a heat exchanger. The wherein the first temperature sensor serves to register a temperature in the feed line of the heat exchanger and the second temperature sensor serves to register a temperature in the drain line of the heat exchanger; wherein the computing means serves to calculate, by means of the measurement signals output by the flow sensor and the first and second temperature sensors, amount of heat exchanged.
