| Overview
The MyStat series has undergone a thoughtful evolution from MyStat v1 to MyStat v2, enhancing functionality while maintaining its familiar and user-friendly design. Both versions are designed to serve as reliable control interfaces for HVAC and automation systems, but the upgrades in version 2 make it more versatile for modern building management needs.
| Physical Design
Both MyStat v1 and MyStat v2 share an identical mechanical design, ensuring compatibility with existing installations. Key physical attributes include:
Circular mounting plate with central cutout for module connection
Integrated bubble level for installation alignment
Dual terminal blocks for wiring access
Standard mounting slots and screw holes
| Electrical and Functional Comparison
| Parameter | MyStat v1 | MyStat v2 |
|---|---|---|
| Relay Outputs | 4 relays | 3 relays |
| Analog Outputs | 1 analog output | — |
| Universal Outputs | — | 2 universal outputs (That can be used as additional relay output as well) |
| Universal Inputs | 1 universal input | 1 universal input |
| Mounting Compatibility | Compatible with MyStat series modules | Compatible with MyStat series modules |
| Power Supply Interface | Same as v1 | Same as v1 |
| Functional Enhancements in MyStat v2
Universal Output Support:
MyStat v2 features two universal outputs that can function as either analog or digital signals, depending on the configuration.
This replaces the single dedicated analog output in v1, providing improved application flexibility.
Optimised Relay Configuration:
The number of relay outputs has been reduced from four to three to accommodate additional universal outputs.
Each relay maintains the same electrical characteristics and switching capacity as in v1.
Backward Compatibility:
MyStat v2 maintains identical mounting dimensions and connector positions, allowing direct replacement of v1 without wiring modifications.
| Use Case Implications
MyStat v1 is suited for systems requiring a higher number of relay outputs and a single analog control.
MyStat v2 is better suited for mixed-mode systems that require configurable outputs to support analog and digital control signals in a single device.
| Summary
The MyStat v2 base plate introduces enhanced flexibility through universal outputs while maintaining the mechanical and electrical consistency of the MyStat v1 platform. This design evolution allows seamless migration to advanced control capabilities without altering installation procedures or compatibility with existing MyStat components.
