AS 611 central controller
Storage heater actuation by microcomputer
The AS 611 is a charge controller featuring ultra modern microcomputer technology. An automated model the AS 611 calculates the charge volume for electrical storage heaters as a function of outdoor temperature and residual heat. It is suitable for actuating storage heaters with thermomechanical charge regulators (heatable liquid bulb thermostats, capillary sensors, thermal contactors).
In addition to A1 signal derivation and optimization the AS 611 is pin-compatible with the predecessor model AS 511, featuring in addition a separate contactor output. The charge controller’s functions are tested at the buttons “LS” and “E2”, which are pressed at the same time. In addition, day recharging can be suppressed (TS) at a temperature set between -10 °C and +10 °C.
