1. Installation manual KIMA ZONE 50 a ae ee Version 3 LCD Display Red increase temperature Programming button Blue decrease On Off temperature switch ZONE 50 is an electronic thermostat for electric underfloor heating system with external floor sensor ZONE 50 can be installed in standard wall box or flush mounted on the wall with an external frame box ZONE 50 controls and regulate the floor temperature to achieve the best room comfort ZONE 50 is using the adaptive PWM and PI technics to to give the best performance and to extend ZONE 50s lifetime ZONE 50 should not be used to eliminate over temperatures in the floor construction The only way to eliminate overtemperatures is to design the floor construction with the right W m and compensate for the floor constructions thermal insulation and the Wattage per linear meter Warm Floor Heating Cable or Wattage per square meter Warm Floor Mat If the buildings insulation properties is poor it can be compensated with another external heat source If ventilation heat pump air condition are chosen as the external heat source it is important that the temperature setting for this heat sources will not be lower than the floor temperature this will save energy The under floor heating construction should never be exposed to high temperatures to elimi nate the risk of fire The worst situation will be when the construction have a high power output per sqm floor and the floor construction i2.
