This article presents the results of the simulation of an automatic control system for the heat supply of a greenhouse complex with a geothermal heat source, conducted in order to study the possibility of geothermal heat supply system automation. Scilab version 6.1 was used for simulation. Based on the results of the simulation, the optimal mode of the automation system function of the heat exchanger primary circuit was developed and implemented. Reagentless treatment of geothermal water in the heat supply system with an acoustic–magnetic device (designed and patented by the authors of this paper) can significantly reduce the intensity of scale formation in the heat exchanger and geothermal heat supply system equipment. It provides conditions for the automation of geothermal heat supply systems of greenhouses with a surface heat exchanger. Using an automation system allows greater accuracy and reliability in maintaining the required temperature regime (18–20 °C) in the greenhouse, reduces the frequency of system shutdown for unplanned cleaning of the heat exchanger and equipment, reduces the complexity of manual operations of heat exchanger and equipment maintenance (removal of sludge, scale) and reduces the economic costs of transportation and heat consumption.

The purpose of the study is to test the hypothesis about the possibility of using telemetry data to identify heat supply objects. The article considers 4 models approximating telemetry data. Determination coefficients and standard deviations were used to select the best model. The residuals were analyzed for randomness, and the absence of shifts and trends. The consistency of the frequency distribution of the residuals with the normal distribution was checked. The significance of the coefficients included in the approximating functions is estimated. Regression analysis was used to obtain the coefficients of 4 models for each of the 7 objects. The Pearson test confirmed the consistency of the distribution of the residuals of one of the models with a normal distribution for all objects. The significance of the coefficients included in all models was confirmed using Student’s t-distribution. The proposed models take into account the flow rate of the coolant and the temperature of the outside air. The dependences obtained do not contradict the physics of the process, both in the field of observation and beyond its boundaries. With certain restrictions on the coefficients of the model, it is possible to obtain numerical values of the parameters of heat supply objects - the average temperature of the indoor air and the required heating load, which confirms the hypothesis that telemetry data can be used to identify the parameters of heat supply objects.
