EC Electronic Controller Trickle & Boost 149 POT

The Elta 149-POT-10-TB is a 0-10V potentiometer speed controller for EC fans with a trickle and boost switch. The fan runs at a set trickle speed and steps up to a set boost speed when the switch is operated.It shares Elta's 149-POT-10 platform with the MI version and is listed for EC fans and variable speed drives (inverters). It provides the speed signal only; the fan keeps its own mains supply. 0-10V EC controller Potentiometer speed control Trickle and boost switch What it is best used forEC extract or supply fans that should run quietly at a background rate and be boosted by hand: kitchens, toilets and washrooms, meeting rooms, changing rooms and small plant rooms. It suits Elta's EC box, inline and mixed flow fans, such as the Jetflow SJMF and Hideaway SH.It is not for ordinary AC fans, which need a mains voltage speed controller. If the boost should come from a BMS, PIR or sensor rather than a local switch, or you need a fan fail relay, use the 149-EC-TB.Why choose this over alternativesCompared with the 149-POT-10-MI, the TB adds the trickle and boost switch, so occupants can raise the airflow without touching the commissioned settings. Typical fans on eFans: Jetflow SJMF 150, Hideaway SH150 and SSDL200.For BMS enable, remote boost by volt free contact, a 0-10V sensor input and a fan fail relay, the 149-EC-TB is the step up.Installation notes Wire the 0-10V output to the fan's control input as shown on the fan's Elta wiring diagram, keeping control cable separate from mains cable. Set the trickle and boost speeds on commissioning so trickle meets the background ventilation rate and boost meets the purge rate. Isolate the fan's mains supply before connecting the control wiring.
