E8.0324, heating control Kromschröder

Elfatherm E8 is a digital heating controller which has been designed for installation in heating boilers.
In addition to the weather-dependent control of boiler (single or dual
stage) and the heating circuit, it also controls the hot-water supply.
The Elfatherm E8 series is equipped with max. 11 output relays which cannot only be used for a dual-stage boiler, 2 mixed heating circuits and a hot water pump but also for two additional tasks.
The E8 series offers control algorithms for special applications such as fixed value control and swimming pool heating.
Quick and easy programming is ensured thanks to a clear parameter
structure, illuminated displays and a 14-digit text display.
To ensure downwards compatibility either 1 kOhm PTC or 5 kOhm NTC sensors can be used. With all types with a storage tank sensor, the water
temperature control through switching the pump is only enabled by the timer program. A second timer channel switches the circulation pump irrespective of the enable times of the hot water program.
E8.0234
The heating controller E8.0234 is suitable for single-circuit heating
systems with single or two-stage burners with or without hot water control. The flow temperature is controlled by switching the burner and the heating pump. The controller can be equipped with the analogue remote control FBR or the digital operating module BM 8.
E8.0324
The E8.0324 heating controller controls heating systems with two separate heating circuits. The two flow temperatures are controlled independently, heating circuit 1 (direct circuit) by switching the burner and the
circulation pump, heating circuit 2 by means of a motorised adjustable
mixer. Independent time programs are available for both heating systems. Each heating circuit can be equipped with an analogue or digital remote con trol.
E8.0634
The E8.0634 heating controller is suitable for controlling systems with two-stage burners or two boilers. In addition it controls two heating
circuits with motorised adjustable mixers. The boiler temperature is
controlled according to both heating circuits, the difference between
boiler temperature and flow temperatures of the heating circuits is
adjustable between 5 K and 20 K. Both heating circuits have separate time programs and can be controlled separately by two analogue or digital remote controls.
E8.1124 Expansion module
The functionality of the E series can be expanded to up to 15 mixer modules by using the E8.1121 expansion module. The E8.1121 modules are connected to a heating controller (e.g. E8.0631) via the communication interface. Every E8.1121 expansion module controls max. two independent mixer circuits. The E8.1121 can also be used as independent mixer controller, without being connected to other E8 units. This setting requires an outdoor sensor.
