Ranco ETC Series line voltage thermostats provide on / off controls and offer electronic replacements for electrical-mechanical temperature handling equipment in commercial heating, air conditioning, cooling & refrigeration applications. They provide flexibility due to their wide temperature ranges, selectable heating / cooling modes, one & two stage capabilities and / or multi-voltage inputs up to 240 VAC. Further, these thermostats are integrated with LCD read-out displays for sensing temperatures, relay status & control settings and have keypad lockouts to prevent end-user alteration of settings. Additionally, they have IP67 rated sensors for dust & water resistance and are equipped with EEPROM memories to retain control settings during power outages. They feature SPST (single pole single throw) or SPDT (single pole double throw) switches to adjust temperature settings and are available in NEMA 1 & NEMA 4X enclosures, thereby ensuring protection from damages due to water ingress.
