Room temperature controller for pressure (in)dependent, single/dual duct, VAV units, with built in Microbridge air flow sensor.
For damper for cool air, re-heat peripheral re-heat and fan.
The XL10 controllers support 8 triac outputs.
Fan output signal 1 triac configurable for on/off or PWM
Re-heat output signal 1..3 triacs configurable for 3-pt, PWM or single/multistage control
Damper output signal 2 triacs for 3-pt control
Auxiliary output signal 1..3 triacs for up to 2 maintained outputs (1 triac each) or up to 1 maintained (1 triac) + pulsed output (2 triacs)
Control functions cooling only, heat/cool change over, cooling/reheat seq. with constant or modulating reheat airflow, cooling /radiator heating seq. with minimum heat, dual duct, dual duct mixed flow; cooling reheat radiator sequence, series/parallel fan, modulating fan
Control functions with 2 controllers dual duct constant volume, dual duct mixed flow, dual duct no flow mixing
Modes of operation occupied, standby, unoccupied, open window, fan fail, summer/winter change over, night purge, morning warm up, smoke purge
Obligatory inputs
1 analogue input for room temperature sensor NTC20k; or apply additional XL10-module with built in sensor on dedicated input terminals
