This reduces buildup of pressure within the supply and also helps reduce the noise that is caused by these high air pressures and velocities, as well as maintains a constant volume of air (CFM) through the duct system.

When the static pressure rises above 0.3”W.C., the SPS will power the motorized by-pass damper open.\u003c\/li\u003e\n\u003cli\u003eAs the by-pass damper opens the duct static should decrease below this higher setting of 0.3” and as it does the damper stops. If other zone dampers open and the static continues to fall below the lower setting of 0.2” W.C., the by-pass damper will close. The two setpoints of 0.2” and 0.3” and the SPST contacts for each, provide the control for the bypass damper to truly modulate to prevent excessive static in the system.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cul class=\"tabs-content\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003ca title=\"manual\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/files\/SPS.pdf?v=1674873686\" target=\"_blank\"\u003e\u003cimg alt=\"Manual\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/files\/3_962c143d-be16-4728-95d1-009109e43a36.png?v=1647307385\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hydro Solar Innovative Energy","offers":[{"title":"Default Title","offer_id":44865294762230,"sku":"50080501","price":162.86,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0010\/8458\/8093\/products\/sps-static-pressure-switch-38550496674038.png?v=1674873950"},{"product_id":"by-pass-eliminator","title":"BPE - By-Pass Eliminator","description":"\u003c!-- more --\u003e\n\u003cul class=\"tabs\"\u003e\n\u003cli class=\"active\"\u003eDescription\u003c\/li\u003e\n\u003cli\u003eTechnical Dcouments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul class=\"tabs-content\"\u003e\n\u003cli class=\"active\"\u003e\n\u003ch2\u003eIntroduction\u003c\/h2\u003e\n\u003cp\u003eThe Bypass Eliminator™ (Model BPE) Control is an interface between a ZONEFIRST Zone Control Panel and its zone dampers.

The BPE uses an air sensor in the duct system on the supply side and before all zone dampers so it can monitor the systems static pressure, whenever the blower is running. The zone dampers are now wired directly into the BPE and not the zone control panel. The BPE has 4 zone inputs where the damper outputs of the zone control panel will plug-in on the BPE. \u003c\/span\u003e\u003cspan\u003eThe zone control panel controls the zone dampers through the BPE. The BPE includes 10 feet of pressure tubing (which can be cut down to size), as well as a duct probe, and four 7 foot telephone cables to interface the BPE with the zone controller. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe BPE controls up to 4 zones on a single HVAC unit and up to 10 dampers per zone on the output terminals. When the BPE gets a signal from the Zone Controller that a zone damper is to be powered open it immediately opens the corresponding zone damper(s) on the output terminals. Anytime the BPE’s pressure sensor detects the pressure in the supply plenum is higher than the Upper Limit Set Point it will modulate the closed zone dampers open to relieve the excess pressure into those zones. As these dampers modulate open the air pressure will drop below the high set-point and the zone dampers stop. When the BPE’s pressure sensor is below than the Lower Limit Set Point it will close the zone dampers. Once the pressure has equalized to higher than the Lower Limit set point and lower than the Upper Limit set point the BPE will signal the dampers to stay in their current position. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe LCD Display will display the status of the zones OP (open), CL (closed), or a number from 01 to 99 to indicate what percent the zones that were in the closed position were modulated open in order to relieve the excess air from the ductwork. If a zone is available for modulation that means that the Zone control board is sending a close signal to the BPE.
