Distech RTU control

[globe trotter]

Help me
Question 1:
Am I correct that Distech has no NVI for heating, cooling setpoints separately in their RTU-L (roof top controller)? The one NVI setpoint that they do have is for the average between the two which really doesn’t tell me anything for sure (NVISetpoint). The VAV-l is the same way.

Is their no way to bind individual heating, cooling, occupied and unoccupied setpoints to the network?


Question2:
On the EC-67 (free prog) it does have an Optimum start however it is bound to the scheduler in the controller. (No way to use an NVI_TOD_event). So I'm stuck using the scheduler in the controller that I can not change setting of from the network (NO NVI for event settings)

Is their any way to use a free prog Optimum start with a schedule I can edit from the network?

Re: Question 1: You are correct. There is no nciSetpoints in the RTU-L. I typically use nviSetptOffset for user interface purposes anyway. That ensures that the deadbands and offsets remain correct. The new ECC-VAV has nciSetpoints and I'm sure the new RTU controller will as well.

Re: Question 2: No help here, really. Can you calculate an optimum start in whatever controller your schedule is coming from? Of course, the EC-67 schedule can be edited over the network using the plug-in, but I assume that won't work for you. Bear in mind if you do end up using the EC-67 scheduler you should bind the time input to a real time clock as the EC-67 has none.
