The compact FTO11 and FTD011 Series of tamperproof thermostats come with a fixed set point and are DIN-rail mountable. The modules are color coded: Red for normally closed models (thermostat opens at temperature rise) and blue for normally open models (thermostat closes at temperature rise). Several different fixed temperature set points are available. The units come with two thermostats: one normally closed (NC) and one normally open (NO) or two normally open (NO).
