2.3. Post-heatingFor most of the year, heat recovered from the air being extracted is enough to warm thecold air coming from the outside to a suitable temperature. If the heat of extract air is notenough, air coming from the outside may be heated further with the post-heating radiatordelivered with the unit.Vallox 132 E model (electric post-heating)VALLOX 132 E comes standard with a 1200 W electric radiator (1) for heating supply air.The temperature of supply air is adjusted at the thermostat regulator (B) located inside theunit behind the cover plate. Temperature adjustment range is +0...+25 °C. Supply airtemperature will not go below the adjusted value.It is advisable to set the thermostat at 0 °C in summer. In this case, the radiator does notheat air.Vallox 132 E VKL model (water-circulating post-heating)VALLOX 132 E VKL model has a water radiator (3) for post-heating. It is regulated usingON/OFF control. The circulation pump is put on in autumn, when the heating season hasstarted, and off in spring when the weather is warm. The temperature of supply air can alsobe adjusted with a separate self-actuated thermostat (not included in the unit delivery). Indetached houses, it is customary to use water/glycol mixture as the liquid in order to preventthe freezing of the radiator. Heating of air depends on the temperature of the water/glycolmixture flowing in the radiator and on the air flow rate.If it has not been considered appropriate to build a water/glycol circuit (schools, officebuildings etc.), the radiator may have been connected directly to the radiator network.Supply air temperature is then regulated by the temperature controller of the radiator networkor by a separate self-actuated thermostat.A post-heating radiator connected directly to the radiator network runs a risk of freezing(see Section 2.4.2.). For antifreeze, see Section 2.4.ACBVALLOX 132 E/VKLINSTRUCTIONS FOR USE5 © VALLOX • We reserve the right to make changes without prior notificationConnection box cover plate1 2Vallox 132E RVallox 132 E VKL R453Thermostats (behind cover plate)Vallox 132 E thermostats(electric post-heating radiator)A Antifreeze thermostat of heatrecovery cellB Post-heating thermostat(regulation of supply airtemperature)C Preheating thermostatVallox 132 E VKL thermostats(water-circulating post-heatingradiator)A Antifreeze thermostat of heatrecovery cellB Post-heating antifreezethermostatC Preheating thermostat
