GB142 Applications Manual
Unmixed Heating Zone & Low Loss Header Module
WM10
The WM10 has two functions:
1. Runs one unmixed heating zone
2. Controls the hydraulic separation between the boiler loop
and system loop in systems with a low loss header (LLH)
Features of the WM10:
• In an unmixed heating zone a separate timer program can
be selected.
• Keyed and color coded connecting plugs
• Communication with EMS boiler-data bus
• Mounting: In the boiler or on the wall
• LED indicator for mode of operation
• 1 module per heating system
• 120V supply
• Input: 1 x Heating Zone Supply Sensor or System Supply
Sensor
• Output: 1 x Heating Zone Pump 120V or System Pump 120V
Solar Thermal DHW Module SM10
The SM10 Module integrates a Solar Thermal DHW system with
an EMS boiler system which provides significant energy savings
for DHW generation. The integrated system knows when solar
energy is available and reduces boiler run time and boiler starts.
Features of the SM10:
• Keyed and in color coded connecting plugs
• Communication with EMS boiler-data bus
• Mounting: In the boiler or on the wall
• LED indicator for mode of operation
• 1 module in a heating system
• Solar pump modulation 20-100% to maximize solar gain
• 120V supply
• Input: 1 x Collector Sensor
1 x Solar Tank Sensor (Bottom)
• Outputs: 1 x Solar Thermal Pump 120V
