Azel SP-83 and 3 units of D-508F Floor Heating Thermostats: 3 ZONE CIRCULATOR PUMP CONTROL (SWITCHING RELAY) WITH PRIORITY FOR FOR HYDRONIC RADIANT FLOOR HEATING SYSTEMS AND 3 UNITS OF NON-PROGRAMMABLE DIGITAL FLOOR HEATING THERMOSTATS The i-Link series 3-zone circulator pump controller is operated by low voltage thermostats or any other low voltage controllers having an SPST switching action. The i-Link controller provides intermediate switching to permit up to 3 circulators and a boiler operating control in a multi-zone hydronic heating system. Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with timer prevents freeze-ups in the event of a priority zone failure. Unique power surge protection to avoid damage to the unit and ensure continuous control operation. The panel provides EZ screwless terminal blocks for connections to the thermostats. LED indicators on the front panel provides functional status and easy troubleshooting. In addition, a system circulator is turned on whenever any zone calls for heat. Product Features and Benefits: * Front panel indicator lights * Field selectable priority * Unlimited zone expansion * Capable of turning on extra system circulator * Compact and modern design * Fuse protection * Power surge protection * Safety design with all electronic components hiding behind the enclosure * Simplified wiring * Contractor friendly PCB layout * High Capacity Field Replaceable Transformer * 24VAC transformer output with common terminal provides compatibility with electronic thermostat * RoHS(Restriction of Hazardous Substances) compliant means this thermostat is Eco-Friendly * Universal thermostat compatibility * 100% Factory Tested * Extended 3 year warranty D-508F: NON-PROGRAMMABLE DIGITAL SLAB SENSING THERMOSTAT FOR HYDRONIC RADIANT FLOOR HEATING Product Info: www.azeltec.com ....read more

What is Hydronic Expansion?
Hydronic expansion tanks are diaphragm type tanks designed to keep system pressures below relief valve settings. Hydronic expansion tanks absorb the expansion of water in residential or commercial hydronic (forced hot water) heating and cooling systems. Without hydronic expansion tanks, the system will quickly over-pressurize resulting in added stress to the various system components. Hydronic expansion tanks protect safety valves from failing or wearing out quickly, avoids valve stem and ball seal leaks, prevents wasted BTU’s and vastly extends water heater life.

Technical Features

  • Certified synthetic SBR rubber diaphragm
  • MIG welding eliminates interior rough spots and sharp edges
  • Each tank is factory leak tested to ensure tank integrity
  • All diaphragms designed to maximize drawdown
  • External baked epoxy-polyester coating provides a durable appliance finish
  • Welded side outlet allows easy and quick installation
  • Protected pre charge valve eliminates potential leak path
  • Low profile tank design with full membrane depth eliminates stretching of diaphragm, providing increased life cycle

Additional Description

  • Shell: Carbon Steel
  • Connection: Carbon Steel
  • Diaphragm: SBR Synthetic Rubber
  • Color: Gray

Operating Conditions

  • Max. Operating Pressure: 60 PSI
  • Operating Temperature: 210 Degrees Fahrenheit
  • Factory Precharge: 12 PSI
  • Warranty: 1 Year

Specifications

  • Model Number: FTH30
  • Tank Size: 4.8 Gallons
  • Tank Weight: 6.8 Pounds
  • Connection Size (National Pipe Thread): 1/2 Male Iron Pipe (MIP)
  • Dimensions (LxWxH): 12 x 12 x 16
  • Acceptance Volume: 3.0 Gallons
