Controllers

Simna controllers are fully-preprogrammed and ready to use solutions for heating ventilation and air conditioning (HVAC) control applications


CA controller

Simna CA is a controller designed for air handling units (AHU) and supports various system configurations. AHU can either be with or without heat exchanger, have a recirculation section and be single or double air flow with direct or constant air volume (CAV) control using integrated pressure sensors. At one time, up to 2 heaters and 2 different types of coolers can be controlled by selectable priorities and can be further expanded by modules.
All functionality is pre-programmed and ready to use. Only simple configuration is required using integrated web server menu.

EA-V module

Simna EA-V extension module provides optimal system installation by reducing wires lengths to the CA controller. Module is designed to be installed in the air handling unit (AHU) section at nearest point to the sensors and actuators, ensuring shortest cables and easiest installation. Module communicates with main controller using 4 wires cable.
It also provides additional functionality due to additional I/O ports.

EA-P module

Simna EA-P extension module provides possibility to control additional air heater or cooler from the CA controller. Various types of heaters and coolers are supported, including 4 stage powerful electric heater with modulating control within entire heating range.
Main controller can control air heater or cooler as additional stage to the air handling unit (AHU) or as independent zone having separate temperature setting point to it.
