The use of the EBC 12 is not restricted to any type of fuel or type of heating appliance. When the appliance thermostat closes and calls for heat, the control will send maximum voltage to the chimney fan or VFD. When the necessary draft is achieved, the control will allow boiler firing and regulate the voltage... - Page 4 3001435 05.12 2.

Page 6: Mounting Of Transducer
3001435 05.12 3.3 Mounting of Transducer Attention must be paid to the location of the transducer. The transducer can be mounted in any orientation but prefer ably with the pressure ports facing down. The transducer should be mounted within six (6) feet of the stack probe. Fig. 4 3.4 Mounting of Stack Probe The probe (Fig. - Page 7 3001435 05.12 4. Electrical Installation 4.1 General Danger: Turn off electrical power before servicing. Contact with live electric components can cause shock or death. EBC 12 is designed for 1x120VAC power supply only. Fan output is regulating on the neutral side and cannot be connected to other circuits. The control can be used in two ways: • Connected so the fan runs continuously independent of appliance operation (see paragraph 4.2). • Interlocked with an appliance so the appliance operation indirectly controls the fan operation (see paragraph 4.3). In both cases the control will still monitor and maintain a constant draft. There are two types of safety systems available: • Integrated Proven Draft Switch (standard).
- Page 8 3001435 05.12 4.2 Continuous Chimney Fan Operation Fig. 7 shows how to connect a chimney fan to the EBC 12 if continuous operation is needed: • Connect the power supply to terminals 1, 2 and 3. • Jump terminals 5 and 9. • Jump terminals 6 and 8. • Connection to the appliance(s): - Connect the start signal from the burner to terminals 14 and 15.
- Page 9 The control can be interlocked with an appliance in two ways: It can be interlocked directly with an appliance control, or with a dry set of contacts. Interlock with Burner Figure 8 shows how an appliance control signal (10-120V AC/DC) is connected to the EBC 12: • Connect the power supply to terminals 1, 2 and 3. • Connection to the appliance: - Connect the boiler start signal to terminal 4.
- Page 10 3001435 05.12 Interlock with dry set of contacts Figure 9 shows how a dry set of contacts is connected to the EBC 12: • Connect the power supply to terminals 1, 2 and 3. • Connection to the appliance: Connect the dry set of contacts to terminals 6 and 8. Jump terminals 4 and 9.

3001435 05.12 4.4 Connection to a Variable Frequency Drive To connect the 3-phase fan and variable frequency drive (VFD), connect the VFD to terminals 25 and 26 of the EBC 12. DO NOT connect the fan directly to the control. - Page 12 3001435 05.12 4.5 Integrated Proven Draft Switch with External Proven Draft Switch Backup Fig. 12 shows how to connect a external Proven Draft Switch (PDS) to the EBC 12. The external PDS is a backup to the integrated PDS and both must be satisfied by sufficient draft to release the appliance: • Remove the factory installed jumper over terminals 16 and 18. • Connect the switch to terminals 16, 17 and 18 as shown on Fig. 11.

3001435 05.12 5. Startup and Configuration 5.1 General Prior to start up please review the paragraph below titled Dipswitch settings. Dipswitch settings Prior to starting the system, check to see if the dipswitch settings are as required: • Default factory setting: All OFF • If the factory setting must be changed, the black cover plate must be removed to gain access to the dipswitches (see Fig 12-A): 1. - Page 14 5.2 Setting Operating Pressure The pressure setting of the EBC 12 must be adjusted to assure proper draft for the heating system. The display (Fig. 13-C) has two functions. It can show what the draft set-point is, and it can show what the actual draft is.
