+Housing for installation on DIN rail - D2MG. Occupies only 2 DIN modules. The 220V > 5V power supply is already on the board, so additional power supplies are not needed.
+To save money, 2 levels are ordered as one board. After manufacturing, the boards need to be divided into 2 parts - upper and lower.

 #### Ratios:
 ***N*** - heating curve coefficient. The coefficient is selected individually, depending on the insulation of the room, the heated area, etc.<br>
-Range: 0.3...10, default: 0.67, step 0.01
+Range: 0.3...10, default: 0.7, step 0.01
 
 
 ***K** - сorrection for desired room temperature.<br>
-Range: 0...10, default: 1, step 0.01
+Range: 0...10, default: 3, step 0.01
 
 
 ***T*** - thermostat correction.<br>
-Range: 0...10, default: 5, step 0.01
+Range: 0...10, default: 2, step 0.01
 
 #### Instructions for fit coefficients:
 1. The first thing you need to do is to fit the curve (***N*** coefficient). If your home has low heat loss, then start with 0.5. Otherwise start at 0.7. When the temperature inside the house stops changing, increase or decrease the coefficient value in increments of 0.1 to select the optimal curve.<br>
