Failure to do so may void the warranty. Unpacking Unpack the DIP-1C and inspect contents for damage. Should the contents appear to be damaged, contact your local distributor to return the equipment. The package should contain the following standard items:... -
Page 9: General Installation Guidelines
DIP-1C INSTALLATION General installation guidelines DIP-1C Module It is recommended to install the unit in a hallway to limit the DIP-1C exposure to noxious gases. In order to avoid condensation problems inside the module, it is recommended to install the DIP-1C on an inside wall. If it is not possible, use spacers to have an air gap between the wall and the DIP-1C. -
Page 10: Electrical Power
DIP-1C INSTALLATION Electrical Power Protection from electrical surge should be included in the planning of each installation. It is strongly recommended to have a backup power source to ensure life- sustaining conditions in case of power failure (see figure 2). -
Page 11: Connection Procedure
DIP-1C INSTALLATION Connection Procedure Detailed Wiring Diagrams Typical Power Backup Wiring A backup relay (DPDT) connects to the power source 1 in normal operation but will switch to the power source 2 if source 1 is disabled. The backup relay should be selected to ensure it is able to support the required power load. -
Page 12: Typical Alarm Connection Wiring
DIP-1C INSTALLATION Typical Alarm Connection Wiring The DIP-1C provides a normally closed dry contact to set off an alarm (potentiometer problem, power loss or other malfunctions). It may be connected to an alarm system or directly to a siren and /or auto-dialer. -
Page 13: Powering Up Procedure
There are two ways to download a configuration in the DIP-1C. 1) Downloading by powering down. A. Ensure the power source of the DIP-1C is OFF (flip the circuit breaker on the distribution panel). B. Remove the faceplate screws and lift up the cover. -
Page 14: Uploading The Configuration
D. When the downloading procedure is complete, remove the configuration chip (MMX) and place it in the bottom part of the enclosure or in another safe location. Once the MMX Chip is removed, the DIP-1C starts up and executes the configuration. -

Page 22: Ventilation System Overview
DIP-1C USER’S GUIDE Ventilation System Overview The DIP-1C is used to control an inlet according to the information received from one or two controllers. The inlet will open progressively according to the ventilation level. Some position can be influenced by the outside temperature. -
Page 23: Normal Mode Settings
Winter Minimum Position (POS 1) These parameters will only appear if the outside temperature is used on at least one of the units connected to the DIP-1C. Winter Minimum Position This parameter is used to adjust the minimum opening position when the Outside Temperature is equal to or below Winter Temp. -

Page 25: Unit 1 Stage Position (Pos 4)
DIP-1C USER’S GUIDE Unit 1 Stage Position (POS 4) These stage positions will only appear if the corresponding stages are used as ventilation stages or as a mist stage with a 100% duty cycle. Stage 3 Position 3-POS This parameter is used to establish the position the inlet will take when stage 3 of unit 1 is activated. -

DIP-1C USER’S GUIDE Unit 2 Variable Position (POS 5) These positions will only appear if unit 2 is activated by setting DIPSW2 to ON (see DIP Switches and Slide Switches Table page 36). Variable 1 Start Position 1-STR This parameter is used to establish the position the inlet will take when variable 1 of unit 2 runs at its minimum speed. -
Page 27: Unit 2 Stage Position (Pos 6)
DIP-1C USER’S GUIDE Unit 2 Stage Position (POS 6) These stage positions will only appear if unit 2 is activated by setting DIPSW2 to ON (see DIP Switches and Slide Switches Table page 36) and the corresponding stages are used as ventilation stages or as a mist stage with a 100% duty cycle. -
Page 28: Inlet Calibration (Pos 8)
DIP-1C USER’S GUIDE Inlet Calibration (POS 8) Inlet Set Low Limit This parameter is used to set the low potentiometer limit for inlet calibration. This will effectively define the lowest possible value for the inlet’s potentiometer. To obtain this value, close the inlet completely using Manual Override. -
Page 29: Alarm Code (Pos 10)
DIP-1C USER’S GUIDE Alarm Code (POS 10) Alarm Code This setting displays the alarm condition. This parameter displays 0 when no errors have been detected. This indicates that the module has operated properly since it was powered up or since the Alarm Code was last cleared. -
Page 30: System Mode Settings
This parameter is used to set the position the inlet will take when no ventilation stages are activated and the Outside Temperature is not used. This parameter will appear only if none of the units connected to the DIP-1C use an outside temperature probe. This parameter is adjusted in 1% increments from 0% to 100%. -
