Manufacturer: Azel Technologies Inc. Brand: Azel Technologies Inc. Model: SP-82

The i-Link series 2-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 2 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 * Priority timer for protection of a priority zone malfunction an...

Manufacturer: Azel Technologies Inc. Brand: Azel Technologies Inc. Model: D-508F

D-508F digital non-programmable hydronic radiant floor heating heat only thermostat is designed to control either ambient(air) temperature (A Mode) or floor temperature (F Mode) or a combination of ambient temperature with floor temperature limits(AF Mode). An auxiliary remote sensor is provided to measure slab temperature in order to control the floor temperature(within maximum and minimum limits in AF Mode). It can also be used for sensing the outdoor temperature in A Mode. FEATURES: Large LCD display QuickSet feature allows instant setpoint adjustment without entering the SETTING mode Selectable display in °F or °C On/Off switch to shut off relay output or shutdown the thermostat at end of heating season for added security EEPROM memory retains control settings in the event of a power failure Lockout mode to prevent tempering by unauthorized personnel One stage heating application Backlit option: Auto (60 sec.)/OFF/ON Supplied with 10ft P-01 floor sensor SPECIFICATIONS: Display Format: Liquid Crystal...

Manufacturer: Azel Technologies Inc. Brand: Azel Technologies Inc. Model: D-502F

Azel Technologies introduces 500 series electronic programmable thermostat that utilizes the lastest digital technologies for residential and light commercial systems. D-502F is designed to control the floor temperature in Radiant Floor Heating Systems. It comes with a 10 ft sensor probe. The 500 series can accurately control the temperature within one degree.

The boiler and radiation installed in your house are designed to keep you warm on the coldest day of the year. For every other day, your heating system is essentially larger than it needs to be. With conventional boiler controls, this "oversized" boiler burns more fuel than is needed to keep the house warm. The new Fuel Smart HydroStat control uses Thermal TargetingTM technology to analyze thermostat activity and continually evaluate how much heat the house requires. When it is very cold outside, the heat demand is high and the Fuel Smart HydroStat raises the boiler's temperature to provide needed heat to the home. When the outside temperature is milder, the heat demand is lower. During these periods, the Fuel Smart HydroStat lowers the boiler's temperature - saving fuel - while the more moderate boiler temperatures provide comfortable and more even heating. The principal of regulating boiler temperatures based on heating loads is not new. It has been used for decades with studies demonstrating average annua...
