In part one of my two part interview with Moncrief’s Phil Mutz, we discuss programmable thermostats. To the best of my knowledge, Phil is the first person in Atlanta to install the new NEST Programmable Thermostat.
In this video excerpt from a HVAC training class on refrigerant recovery machines and methods, Bacharach’s Jim Mowery walks us through Bacharach’s approach to refrigerant recovery. One of the things that makes Bacharach unique is that they have a complete line up of refrigerant recovery machines. So it does not matter if you are working on residential, commercial, or industrial units Bacharach has a machine for you. [Read more…]
Honeywell has announced they are introducing a series of integrated combustion panels to go along with the awsome Delphi release from last year. These new panels will incorporate Honeywell’s proven combustion technology into complete panels, making equipment upgrades a snap! All panels will be pre-wired, pre-tested, and a built in a certified UL panel shop. Made in the U.S.A.
The initial offering will include: [Read more…]
Weiss Instruments has over 100 years experience in manufacturing a complete line of quality thermometers and pressure gauges. One of their products is great for new installations or replacement of industrial glass and bimetal thermometers. It is a vari-angle digital thermometer that is mercury free and light powered. Yes, light powered! It works for chilled, condenser and hot water applications, has a fast response time and is F/C switchable. Its accuracy is within 1% and ranges from -50 to 300 degrees F.
Weiss also offers the first “self-indicating” temperature transmitter that is light powered. Combining their mercury-free solar thermometer with a loop-powered 4 to 20mA transmitter results in a single unit that allows local reading and remote transmitting for HVAC systems, building automation or anywhere local and remote readings are required. Dual sensors offer independent operation for reliability and convenience. It requires one thermowell which saves time and money without sacrificing performance.
The Honeywell T775 Series stand alone controllers have now been on the market for several years. This diverse controller offers the technician a multitude of installation options on one small package.
This controller that stands 8 inches wide by 4 inches wide can be mounted anywhere within 1000 feet of its sensor location and be purchased as a standard enclosure or a NEMA 4X enclosure.
The T775 has an EEPROM that saves all values entered. The date and time values are retained for 24 hours after power loss. After power loss of more than 24 hours values may need to be reentered.
IMPORTANT: If a high limit set point is entered into a T775 controller this value is IRREVERSIBLE !!
Voltage: 24/120/240 note: cannot be used for DC voltages
Set Point Range: -40 to 248 F
T775A and B models: relay outputs from 1 SPDT to 4 SPDT (no analog outputs). Sensor inputs 1 to 2. Floating outputs 0-to 2
T775M models: Modulating with analog outputs of 2-10Vdc or 0-10 Vdc or 4-20 mA or Electronic Series 90. Relay outputs from 0 to 4 SPDT. 2 sensor inputs
