The Pro HVAC Module

Smart-HDL Introduce The Pro HVAC Module

ALL your Air condition connection and control Problems now it solved with Smart-HDL, the New Pro HVAC Module and the intelligent DLP LCD Panel introduce you wide range of control

1 - Don't be confused, you can connect single Compressor Stage, Multi Compressor Stages both in 1 Module.

2 - Safety Running time: adjustable Running Sequences for Single and Multi Stage to safe your Compressor.

3 - Safety ON/OFF Protection: ON compressor, FAN safety adjustable delay time

4 - All Modes, Adjustable Cooling Heating, Auxiliary control.

5 - FAN Control: 3 Fan speeds as Low , Medium , High

6 - No Need Convertor: 24 VAC, 110VAC, 220VAC compressors and fans, all can be connected and controlled to the HVAC relays

7 - VAV control, 0-10 VDC controlling with adjustable High, Medium, Low voltage Output

8 - AHU Control, 4-20 mA output

9 - Auto Mode: to auto select between Cool, Heat, Fan in all your year seasons

10 - Adjustable: Temp sensor calibration built in the LCD panel to fit your real room temp.

11 - Extra sensors: Second Temp sensor/ Humidity input 4-20/0-10 V

12 - Diffrent calculation used LCD temp sensor, HVAC ext temp sensor, or Average between both for big halls.

13 - More control: can be control as master slave thermostat for 1 compressor for many DLP LCD panels

14 - Powerfull: each DLP Thermostat can control up to 8 other LCD Thermostat.

15 - Integration: smart-HDL also can control split AC by IR control, 3rd Party HVAC BMS system by RS232.

Smart-HDL care about everyone in the world, to make your home healthy, saves your energy, educates you, and makes you happier.

“ALL your Air condition connection and control Problems now it solved”

oh really , ALL of them ?

what about zone specific vent actuator outputs ?

only 3 fan speeds ? ever heard of PWM ?
does it have evaporator frost detection and correction provisions ?
how many thermocouples inputs ? just inside the heat pumpts I plan to have 6 , plus at least 3 per room !
how about furnace control, have an input for the photodetector to turn off the ignitor when it’s not needed ? air flow detector to make sure the fan belt hasn’t broken and the core is overheating ? how about multi-fuel systems or fuel heater control ? what I thought you said ALL !!

and where’s the source code anyway ? a general link to your website I couldn’t even find the product in question !!

ok so the reason I reanimated this dead thread is that HVAC is a very important subject that is just perfectly suited for arduino control

and it just happens that HVAC controls are dumb as rocks and most HVAC technicians I met couldn’t tell their coulombs from their dicks ! so I see a hvac-game-changing disruptive technology in arduino’s future and I am sure I am not the first one, except I can’t tell because the arduino forum search is so terrible !! there has to be a least several hvac projects using arduinos at their core, would anyone be so kind as to point them to me

thanks ! (sorry tldr)
