Page 4: Centralised Management By Zone Timer For Comfort Unit
1 CENTRALISED MANAGEMENT BY ZONE TIMER FOR COMFORT UNIT The comfort units (ductable, air handling units or cassettes), which are all independent, are equipped with a V300 control. Each comfort unit has its own comfort temperature sensor. A centralised timer comprising a zone controller and a wired LCD terminal in an electrical cabinet outside the zone enable remote centralised management of this loop. -

▪ Outdoor temperature sensor (depending on options) - To be wired to sensor S1- ┴ (terminal 31-32) - Enables: 1) activation limit for electric heaters on the comfort units 2) the installation to be started in advance for heating ▪ 230V – 10 A max. contact output slaved to a time schedule (auxiliary control): The 230V EH output is then considered as a separate zone and can be switched ON/OFF by the time schedule for this zone (e.g. start-up of auxiliary equipment: extractor, fan, etc.). This zone appears as "Zone 1 6" on the display. ▪ Display keys locked (securing access to operate the installation, etc.) 5 V300 ZONE TIMER PARAMETERS AND DIAGNOSTICS ▪ Two levels are available: - Level 1: settings - Level 2: system start-up Level 2 "System start-up" must be used with care: these settings configure the installation, therefore modifications must only be made with full knowledge of the situation.
