Service Warmers raise ambient temperature

Raise Ambient Temperature to 100% requires bringing individual Service Warmers back online. There is no single master temperature control that completes the objective.

A heating route can progress through 17% → 34% → 61% → 78% → 100% as warmers come online. Watch the objective percentage while continuing the repairs.

02

Follow the warmer markers through the Depot

  1. Pin the Service Warmer objective in the journal and compare the visible fire-marker distances.
  2. Repair the nearest practical warmer, then inspect the areas its heat uncovers.
  3. Look for newly thawed passages. Some warmer repairs melt enough surrounding ice to expose a previously blocked route.
  4. Recheck the remaining warmer markers from your new position and continue the route.

Pack the warmer repair bottlenecks

One Service Warmer repair uses 4 Metal, 1 Light Bulb, 4 Wires and 2 Electronics. Carry these materials as you work through the heating objective.

04

When the heat percentage is still below 100%

Is there one temperature switch that finishes the objective?
No single control finishes it. Restore individual Service Warmers and use the remaining fire markers to continue raising ambient temperature.
Why recheck the route after repairing a warmer?
The heat may uncover a passage through the ice. Inspect that opening, then compare the remaining markers from the new position before choosing your next repair.
