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

The i-Link series Zone Valve Controls simplify the field wiring and yet control up to six zone valves in a multi-zone hydronic heating system. The contractor friendly Printed Circuit Board eliminates the problem caused by incorrect wiring and saves hours of installation time. There would be no more messy look of conventional zone valve installations. Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with Priority Protection Timer ensures other zones get heat every one hour and prevents freeze-ups in the event of a priority zone failure. The End Switch delay timer let the two wire type zone valves fully opened before turning on the circulator. The panel provides EZ screwless terminal blocks for connections to the thermostats and zone valves. In addition, LED indicators on the front panel provide functional status and easy troubleshooting. Features: * Front panel indicator lights * Field selectable Priority * Priority timer for protection of a priority zone malfunction and prevention of freeze-ups in the heating zones * Unlimited zone expansion * Three-minute End Switch delay timer for two wire type zone valve applications. Circulator will start only after the zone valve is fully opened. * DIP switch for easy setup of two wire type zone valve applications. No need to hook up wire jumper on the third and fourth terminals on each zone * Works with two, three or four wire type zone valves and thermostats * Fuse protection * Simplified wiring * Contractor friendly PCB layout * Easy-Connect Screwless Terminals * 24VAC transformer output with common terminal provides compatibility with electronic thermostats * Universal thermostat compatibility * Isolated End Switch and Priority End Switch * Pre-wired terminals for circulator * SPDT Priority zone relay switch (N/O Com N/C). Capable of prioritizing DHW pump in a 2-pump system * 50VA replaceable transformer * Extended three year warranty ....read more

I wrote this book for people who prefer plain-English explanations of how things work. You won’t find much math in this book. No formulas. No mumbo-jumbo. What you will find are simple words of ordinary conversation, and a lot of very easy-to-follow drawings relating to hydronic radiant heating. There are also stories – lots of them! I like to tell stories about the things I’ve seen as I’ve traveled around the US, Canada and Europe, looking at hydronic radiant installations. I’ve seen installers do things the right way and the wrong way, and I learned from them all. I dug into old books as well as the current literature to write this one, and I did my very best to boil down the engineering into understandable terms. This book contains 215 pages of practical, common sense information that you can use right away. I’ve made lots of analogies to things you already know. Hydronic radiant heating doesn’t have to be complicated or spooky. There are rules of thumb that work, and installers are using them with great success every day. There are simple ways to install and control these systems. I’ll show you how. All in all, you’re going to find straight answers to direct questions in this book. I’ve done my best to present a subject that I love in a way that I think you will find both informative and very enjoyable. ....read more
