This reverse-acting controller responds to changes in relative humidity by modulating a pneumatic output signal, which in turn adjusts valve position to maintain the desired humidity level. Pilot-operated for high-capacity applications, the HP970B1007 is built for commercial and industrial environments where precise humidity management is critical. Licensed HVAC and controls technicians are the primary installers of this device.\u003c\/p\u003e\u003cp\u003eThe HP970B1007 is suited for commercial HVAC applications where pneumatic control systems govern humidity in large air-handling or ventilation systems. It mounts in vertical or horizontal orientation, offering installation flexibility in mechanical rooms, air handling units, and terminal equipment enclosures. The reverse-acting configuration means the pneumatic output decreases as humidity rises, making it appropriate for dehumidification valve control or other reverse-logic pneumatic circuits. Both direct-acting and reverse-acting models exist within the HP970 series to cover a range of control strategies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-pipe pneumatic configuration for proportional humidity control\u003c\/li\u003e\n\u003cli\u003eReverse-acting output suitable for dehumidification valve applications\u003c\/li\u003e\n\u003cli\u003eSingle setpoint design for straightforward humidity control loops\u003c\/li\u003e\n\u003cli\u003ePilot-operated construction supports high-capacity pneumatic valve actuation\u003c\/li\u003e\n\u003cli\u003eAccepts vertical or horizontal mounting orientation\u003c\/li\u003e\n\u003cli\u003ePart of the durable HP970 series designed for commercial HVAC service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with pneumatic humidification and dehumidification systems that utilize pneumatic valve control.

Shut off the main air supply to the pneumatic control circuit before disconnecting or connecting any pneumatic tubing. Ensure supply air pressure is within the operating range specified for the HP970 series before commissioning. Follow local mechanical codes and the manufacturer wiring and tubing diagrams when integrating with existing pneumatic control panels.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Type\u003c\/strong\u003e: Pneumatic, proportional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction\u003c\/strong\u003e: Reverse Acting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pipes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoint Configuration\u003c\/strong\u003e: Single setpoint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Vertical or horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP970B1007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":67608155291954,"sku":"HP970B1007","price":1188.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/182557061.webp?v=1790431515","url":"https:\/\/voomisupply.com\/products\/honeywell-hp970b1007-pneumatic-humidistat-reverse-acting","provider":"Voomi Supply","version":"1.0","type":"link"}
