Hoteliers should prioritize thermostats that are guest-friendly, energy-efficient, and compatible with central energy management systems. Features to look for include programmable schedules, occupancy sensing, remote control capability, and limits on extreme set points to balance comfort and cost. Smart thermostats can reduce energy waste in unoccupied rooms while allowing guests adequate control, and those that integrate with building systems help automate efficiency. Tamper-resistant designs also protect settings from being reset unintentionally.
