Fancoil Controls

SoCal_Hydronics

Greetings!

I have begun to use Jaga fancoils more and more in hydronic systems. I am hoping to find some control options besides the ones I already know. The Jaga units support 0-10V variable speed fans, which is great.

I have used Tekmar and Messana and am familiar with Neptronic 0-10V thermostats to achieve variable fan speed.

My latest client is asking for Ecobee stats because he like the WiFi interface. I have looked carefully at the Ecobee literature and though they say the support multispeed fancoil installations, I do not think they output 0-10V .

what else is out there to gove me 0-10V control or even just 5V /10V? I could probably get away two fan speeds

Thanks!

A https://www.workaci.com/product/161?v=6418 looks like it will let you convert one to six digital inputs to an analog output. I've done something similar with a small adjustable DC power supply (power it via G, then adjust the output to the right speed).

There's also this: https://www.datanab.com/products/mbus_io12_lcd-fully-programmable-modbus-i-o-device-with-lcd-display (and similar), which are kinda fun—but will generally mean more work for you, both on the original rollout and any kind of service. I have a discharge air program that will control staged or analog heat/cool, and offers a ΔT setting as well. Like I said; fun, but more work.
