2.1 Survey of the relay allocations
The tabular survey shows the standard relay- and sensor
allocation for the 7 basic systems with their hydraulic posi-
bilities (see relay-and sensor allocation for the basic systems
on page 42).
Explanation: 1.) System 2 / version 1, pump for collector
1 at relay output 1
2.) System 2 / version 2, 2-way valve for
collector 1 at relay output 1
Example:
The controller is equipped with 10 thermostat functions, 5
additional temperature difference functions (DeltaT) and 5
timers.These functions are combined into function blocks
which are allocated to the relay outputs.
