Single and triple-loop universal controller
The UVR61-3 unit has various functions for use in solar power systems and heating systems:
thermostat, differential temperature, and speed control. The desired control function is the result of
the program number that is input.
Overview of functions:
6 sensor inputs
1 output, speed controlled, 2 relay outputs
2 analogue outputs 0-10 V separately switchable to PWM
Each with 3 functions for differential, minimum and maximum
Legionella protection function, collector cooling function
Heat counter integrated, drain-back function, freely programmable timer
Easy-to-read display with various icons
Data line (to analyse the temperature with a PC via D-LOGG or BL-NET)
System function control
Solar start function, collector temperature delimiter, frost protection
Overvoltage protection on all inputs
