Description
The Johnson Controls M4-CVM03050-0P is a Metasys CV Series VAV box controller - a BACnet MS/TP terminal unit controller with 3 inputs and 5 outputs, fitted with an integral damper actuator, a digital Differential Pressure Transmitter (DPT) sensor and an integral potentiometer for damper position feedback.
What the -0P suffix means. Johnson Controls documents it directly: the CVM03050-0P and CVE03050-0P models feature an integral potentiometer to sense actual VAV box damper position. That is the single difference between this controller and the base M4-CVM03050-0, and it is a hardware difference rather than a setting.
Why position feedback matters. Without it, a controller commands the damper and assumes it moved. With the integral potentiometer it reads the actual damper position - which is what allows genuine airflow verification, commissioning proof and fault detection on a VAV box. If your sequence needs to know where the damper really is, this is the variant that does it. Johnson Controls covers the configuration in the M4-CV Series Actuator Feedback Application Note (LIT-12013631).
Point configuration: the model number gives it - 030 then 50, meaning 3 inputs and 5 outputs, 8 points in total.
What the inputs and outputs accept. Johnson Controls documents the CG and CV series point types as follows:
* Analogue input, voltage mode - 0 to 10 V DC
* Analogue input, resistance mode - 0 to 600 kOhm; RTD (Ni1000 Johnson Controls sensor, PT1000, A998 SI); NTC 10k Type L; NTC 2.252k Type 2
* Binary input - dry contact
* Configurable output (CO) - analogue output voltage mode 0 to 10 V DC, or binary output 24 V AC triac
Also on board. The CV series carries a 32-bit microprocessor and an integral real-time clock, which lets the controller hold schedules, calendars and trends and keep running as a stand-alone controller for extended periods if it loses contact with the Metasys network. The controllers are fully programmable with the Controller Configuration Tool (CCT), so custom control sequences are possible, and preloaded applications are also supported.
Where it fits. VAV box controllers sit at the terminal units of a variable air volume system - one per box, regulating the damper and any reheat to hold the zone setpoint, and reporting back to the supervisory engine over BACnet MS/TP.

We hold the Metasys equipment controller range in depth - CV VAV box controllers both with and without position feedback (the base M4-CVM03050-0 and this -0P), the CVE03050-0P sibling, CG general purpose controllers in two sizes, XPM expansion modules, and SNC and SNE network engines to supervise them. Tell us how many VAV boxes you are fitting and whether your sequence needs actual damper position and we will tell you which variant you want.
