Controller for VAV units, Excel 10
 |
| 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 operations |
occupied, standby, unoccupied, open window, fan fail, summer/winter
change over, night purge, morning warm up, smoke purge |
