NT 37-F / NT 37-M: Thermostat (normalement fermé); disjoncteur de contact pour réguler les radiateurs. Le contact s'ouvre lorsque la température augmente.
NT 38-F / NT 38-M: Thermostat (normalement ouvert); Contacteur pour réguler les ventilateurs à filtre et les échangeurs de chaleur ou pour commuter les dispositifs de signal lorsque la limite de température est dépassée. Le contact se ferme lorsque la température augmente.
