EXCHANGING EXPERTISE SINCE 1893 53
Load Control
» Uses the same comm infrastructure
» Standardized on 2 relays (A/C and W/H)
– Low voltage 5amp relay, high voltage, 30amp relay
» Indoor or Outdoor installation
– UL Listed
» Two‐Way communications results in certainty of results
– Monitoring of appliances for “yield”
– Identifying failed or bypassed units
– Identifying “free riders” and tamper conditions
» Downloadable addresses, strategiesand other operating parameters
» Short‐cycle protection for compressor loads
