# Datahall CRAH UMAS 10FSV041206-058-117.00x114.00 TCP
## Brief Introduction
This is first of a kind CRAH, so Modbus maps are different.
BMS Control Source (0:speed, 1:external room temp) and
BMS Enable Source (0:keypad, 1:DI, 2:BMS) sent from PLC/Modscan
PLC code for these CRAHs use Speed Control, i.e. Speed Setpoint sent from PLC/BMS.
Return Air is generally not used for control during normal operation.
Leak Detect alarm is the only alarm that will send unit to FailState.
This is a (9) fan array CRAH unit.
## List of Equipmentt
This cofiguration has been used for these models:
* **Model: 10FSV041206-058-117.00x114.00**: 10-07-25
## Hardware Prerequisites
The code is written for an ESP8266/ESP32-style microcontroller with WiFi capabilities.
* **Microcontroller**: [Firebeetle 2 ESP32.](https://www.dfrobot.com/product-2231.html)

## States and Strategies
Provide a brief description of what variables and strategies were used in this configuraiton
### Standby State
* **CW valve**: **Ramp Strategy** ramp to 0
* **Supply Air temperature**: **Ramp Strategy** ramp to 74
* **Return Air temperature**: **Ramp Strategy** ramp to 86
* **Fan speeds**: **Ramp Strategy** ramp to 0
* **Fan amps**: **Ramp Strategy** ramp to 0
* **Fan run status**: set to 0
### Running State
* **Fan run status**: set to 1
* **Fan min speed**: initialized to 30
* **Fan max speed**: initialized to 100
* **Fan speed**: **Ramp Strategy** dynamically ramps to speed setpoint
* **Fan amps**: **Ramp Strategy** ramp to 15
* **Fan operating hours**: initialize totalizers
* **Supply air temperature**: **Saw Strategy** ramps back and forth between 60 and 100 deg
* **CW valve**: **PID Strategy** adjusts until Supply Air Temperature matches Supply Air Temperature setpoint
### Fail State
* **Fan run status**: set to 0
* **CW valve**: **Ramp Strategy** ramp to 0
* **Fan speeds**: **Ramp Strategy** ramp to 0
* **Fan amps**: **Ramp Strategy** ramp to 0
