PST5 EC - Programmable thermostat

PST5 EC thermostat is designed to control the ARWE, A3RWE and AREX fan speed controllers and the EC motors using a 0-10VDC signal. It has the option of 4-zone 7-day programming, which allows to set the desired temperature in 4 different time zones for each day of the week separately. In addition, thermostat has the ability to automatically turn on and off at a specified time. The choice of one of 4 operating modes allows to use the device in heating, cooling, ventilation or mixed systems. The system is equipped with contacts controlling hot and cold water valves. In the event of power interruptions, the thermostat switches on automatically (auto-restart). PST 5 EC has the ability to set settings using the MODBUS protocol. An additional input allows the connection of an external NTC temperature sensor. The device also allows measuring and displaying the fan speed in case the fan is equipped with an impulse output. The thermostat has great reconfiguration options, which allows it to be used in various cooling and heating installations. Device dimensions: 86x86x25,2mm (H x W x L).
