i need a heating nodule with 0-10v output for a modern heaters and continuous flappers. Is this possible with the current software? And if not, could you integrate it somehow? I am using a heat recovery unit with a continuous bypass. Controlling the temperature with a 0-10v output would really help….
Maybe you could just allow us to connect the heating module to a 0-10v output?
Hey Alaine, thanks for your reply, and sorry for responding so late. I had to deal with a nasty covid infection. Ideally I’d need two modules. Lets start with the more important one for my application. Lets call it the flapper module:
Imagine having two different air inlets (with different temperatures) connected via a bypass flapper that can be controller continuously via 0-10v. So 0v is inlet A only, 10v ist inlet B only and 5v is a 50/50 mix of A+B (and therefore temperatures).
Now id need to assign a temperature sensor to each of the inlets within the new module. And then a temperature setpoint.
Say its 10 degree on inlet A and 30 degree on inlet B. If i set my setpoint to 20 degree, id get a 5v output. Set it to 10 degree and id get 0v output. Set it to 30 degree, i get 10v. Set it to 15 degree, i get 2.5v output and so on. Everything below 10 degree is 0v. Everything above 30 degree is 10v.
In case inlet A is hotter than inlet B, everything is reversed.
The second module would be a „simple“ thermostat featuring 0-10v outputs. I did attach a diagram from another company (S+S RTR-S room temperature controller).
Basically it can run in either cooling, heating or automatic mode. It features a setpoint with K-factor and a neutral zone (with dedicated setpoint and K factor in auto mode) and has separate 0-10v outputs for cooling and heating. I hope the diagram is clear enough. Otherwise please feel free to contact me anytime.
ps: i dont know how to insert an image on here. So here is a link:
