Heating controller for three circuits (control for 2 heating circuits + 1 domestic hot water control). DIN rail mounting. Built in WebServer (WEB UI)
Dimensions: width 213,5 mm, height 93,3 mm, depth 96,8 mm
Weight: 0.7 kg
Protection class: IP 20
Operating temperature: 0 ºC…+40 ºC
Storing temperature: -20 ºC…+70 ºC
Power supply
Operating voltage: 24 Vac, 50 Hz (22 Vac – 33 Vac)
Power required: (15 Vdc output =if not connected) 13 VA, (15 Vdc output = 750 mA) 34 VA
In addition, the operating voltage of 24 Vac and the power requirement of the Triac outputs must be taken into attention. Maximum total current limit is 4A. Then maximum supply power need is 96 VA. (Max 1A/triac pair)
Backup input: 12 Vdc
Current consumption: 300mA / 3,6W (relays not in use), 400mA / 4,8W (relays in use)
Universal measurement input (can be configured) measurement types:
Passive sensors (inputs 1…13) Measurement channel accuracy:
