Summary of Hab Operations: Nominal. Additional current projects:
Hab toilet: Toilet tank has been modified to include a permanently mounted tank rinser directly adjacent to a new fill level sensor suite. Upstream plumbing modified to include inline shutoff valve, allowing for ongoing sensor rinsing as part of crew toilet SOP. New fill sensors mirror original fill levels and are designed to gather data from the tank exterior. New sensor control board has replaced the original and provides fill data to hab dashboard. Tank shell modified to accept new plumbing. Plumbing line anchor locations modified to accommodate water hammer effect of toilet valve operation. Data cable includes metallic wrap as a rodent deterrent. Enzymatic treatment used following sensor placement as part of tank dump cycle, and will also be added to toilet SOP.
U-Deck HVAC fan: New 120V electrical lines run in flexible non-metallic conduit from L-Deck breaker panel to fan control board. Conduit is routed from the top of the panel to the L-Deck ceiling, then to the northeast to a penetration near the galley pantry. Routing continues vertically to the U-Deck ceiling rim and finally to the fan location. The same conduit carries new 24V control wiring from the fan to the U-Deck thermostat. Standard and low voltage lines use a junction box directly above the breaker panel, providing a breakpoint for modification.
Thermostat: Existing smart thermostat entered lockout mode during Crew 331 sol 1 and was replaced with the previous model, restoring function. During fan control tie-in (described above), a fault was detected in the furnace control board. Once a new board has been sourced, function of the U-Deck fan and a new smart thermostat will be confirmed.
