February 2026 — lsst-ts/ts_config_ocs: Delivered configurable HVAC temperature control enhancements to improve safety, efficiency, and maintainability. Implemented glycol safety and maximum limits as a new configuration parameter, tuned M1M3 deltas and cooling/heating rates for better stability, and updated _init.yaml to enable repeatable deployments. These changes reduce manual intervention, enhance reliability, and support scalable deployments in critical environments.

Month: 2025-11. Focused on targeted HVAC configuration tuning for the lsst-ts/ts_config_ocs repository to enhance thermal management performance, stability, and responsiveness. Changes were implemented via YAML config updates and are aimed at reducing latency in thermal control loops while maintaining safe operating margins.

October 2025 monthly summary: Two cross-repo improvements focused on operational readiness and configurability. In lsst-ts/ts_config_ocs, implemented EAS Heating Setpoint Offset Adjustment to raise heating by 0.5C by updating glycol, heater, and top-end delta configurations, supported by commit 1c8cfe54f709a80cd69f4fa0d15d91dc26d29d98. In lsst-sqre/phalanx, enabled full mount functionality by switching from 'ccw-only' to 'full', enabling the mtmount service and retiring the 'mtmount-ccw-only' deployment, supported by commit 20a46aa4c80f851028ae33512016eb1ac1695bf8. Overall, these changes improve environmental control accuracy and telescope mounting capability, reducing manual configuration and operator risk.

September 2025: Focused on configuring the EAS system (lsst-ts/ts_config_ocs) for reliable v7/v8 operation and improving ESS tracking, while mitigating throttling-related performance risks. All changes were captured in committed configuration updates to support reproducibility and future rollbacks.

Monthly summary for 2025-08 focusing on the lsst-ts/ts_config_ocs Thermal Control System Tuning. Delivered configuration updates to ambient sensor readings, setpoint deltas, indoor ESS index (113), and adjustments to setpoint deadbands and heating rates to improve system response to ambient temperature variations. All changes tracked in commit 21b09c91e982d25ef4d021a1af0fd20a9c270c83 ("BS switched ambient sensor to 113").
