Azel I-Link SZ-V4 Zone Valve Controls
Azel 4 Zone Valve Controller with Priority. Unlimited Zone Expansion.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.

Azel Single Zone Switching Relay
Azel Single Zone Switching RelayThe SP-81 universal single zone switching relay is operated by low voltage thermostats or any other low voltage controllers having a SPST switching action. The SP-81 provides intermediate switching to permit up to two separate line voltage loads such as circulators.$52.31 -
Azel Digit-stat DS-60P Digital Temperature Gauge
Digital Temperature Gauge with Two Universal Sensor Probes (Ds-60 and P-01)The microprocessor-based, AZEL Technologies Digital Temperature gauge DS-60 represents the “next generation” in temperature gauge industries. The bold, hi-contrast LCD display ensures accurate temperature reading to the tenth degree and can be easily read from greater distances than the typical mechanical temperature gauge. DS-60 REPLACES TWO mechanical temperature gauges as it can centralize the readings in one spot and simultaneously display the accurate temperatures of supply and return piping on a hydronic heating system. In addition, the solid state temperature sensor probe can be extended up to several hundred feets. The unit is designed to be powered by 24VAC input or by lithium battery. When 24VAC is supplied, the lithium battery enable the unit to work in case of power failure. Its features also include Min/Max memory which shows the highest and lowest temperature after the last reset and instant Fahrenheit to Centigrade conversion. DS-60 is also ideal for any application (EG. Solar heating or Geothermal) that requires quick and accurate response to temperature change, an easy to read display and a wide temperature range.$50.00 -
