Öryggis- og uppsetningarkröfur
Please ensure that these instructions are read and understood before installation. Failure to comply with the instructions listed below can cause product/property damage, severe personal injury, and/or loss of life.

Vinna við tækin
The installation, adjustment, service, and maintenance of this product must be done by a licensed professional heating contractor who is qualified and experienced in the installation, service, and maintenance of hot water boilers. There are no user-serviceable parts on the boiler, burner or control.

Ensure the main power supply to the equipment, the heating system, and all external controls has been deactivated. Close the main gas supply valve. Take precautions in both instances to avoid accidental activation of power during service work.

It is not permissible to perform service work on any component part, ensuring safe operation of the heating system. When replacing parts, use original Viessmann or Viessmann-approved replacement parts.
Ensure that the installation literature of other Vitodens 100 components is referenced.

Input Module Description

What is OpenThermTM
The Open Therm (OT) protocol is a point-to-point communication system that connects a boiler with a room controller. The room unit calculates a heating demand (water temperature request) and transmits it to the boiler. The boiler will adjust the heat input accordingly (low-high modulation).

The Viessmann Input Module is designed to accept a 0-1 OV (DC) modulating input signal from a boiler reset module controller and send this signal to the Vitodens 100 with Open Therm communication. See the chart on the fo//owing page for the signa/ translation protocol of C)- IOV to boiler approximate supply temperature.

Input Module Operating Characteristics

Lægsta binditage signal (from below 0.9 V) to start the boiler (cut-in) — 2.2 V
Lægsta binditage signal to shut down (cut-out) the boiler = 0.9 V

Lægsta binditage signal (from below 0.9 V) to start the boiler (cut-in) — 2.2 V

Lægsta binditage signal to shut down (cut-out) the boiler = 0.9 V

Uppsetning

Remove the left white cover of the Input Module.

Remove the black cover of the Input Module.
Loosen two screws and gently pull the module off its sub-base.

Remove the required number of knockouts. Install supplied strain reliefs and guide wire harness into the terminal box.
Mount the terminal base onto wall close to the boiler.
Make electrical connections. (See wiring diagram on page 5)
Run Input Module communication cable (2-wire 18AWG) through Power Pump Module to boiler control sub-base Terminal X3.3, X3.4 for WBIA series boilers or X21.1, X21.2 for WBIB CombiPLUS series boilers, or to connection terminals X21.1, X21.2 on the Bl HA/BI KA series boilers.
Connect power supply harness to RT terminals in the Power Pump Module Terminals X4.3 and X4.4. Note: Bl HA/BI KA requires an external 24VAC power source (field supplied).

Wiring Diagram WBIA, WBIB boiler series

If needed (service or emergency heat request), a call for heat can be initiated by jumpering Terminal X3.3, X3.4, or X21.1, X21.2 on the boiler control or Terminals 12, 13 on the Input Module sub-base. The boiler will operate as it would with room thermostat operation and will cycle on the adjustable high limit: setting.
Refer to the Vitodens 100 Operating Instructions.

A call for domestic hot water or external heat demand (closing the ST contacts on the PPM of the boiler) has priority over a call from the Input Module. The boiler will operate with a constant setpoint of 780C / 1720F during a call for domestic hot water.

Wiring Diagram BIHA, BIKA boiler series

If needed (service or emergency heat request), a call for heat can be initiated by jumpering Terminal X 21.1, X21.2 on the boiler control or Terminals 12, 13 on the Input Module sub-base. The boiler will operate as it would with room thermostat operation and will cycle on the adjustable high limit setting.

Refer to the Vitodens 100 Operating Instructions.
A call for domestic hot water or external heat demand has priority over a call from the Input Module. The boiler will operate with a constant setpoint of 176 OF (800C) during a call for domestic hot water.
