STAR PUMP RELAY

Boiler and Pump, Logic Module
This is an Intelligent electronic control interface that can switch the
pump and boiler dependant on the requirements of the main wiring
center. This unit is used to protect the boiler and pump and to reduce
cold cycling of the boiler so as to ensure there is a demand for heat
prior to switching on the boiler and pump unit.
Our experience over the years have proved that this reduce excessive
energy usage and ensures better control of the Underfl oor Heating.
The pump module is optional and has the following functions:
- Pump Overun
It can allow the pump to have a run on time of 3 minutes once
sensors have swiched off if required this function can be de
activated using jumpers shown.
Jumper Function
J2-Pump overrun time
ON -OFF
ON - After all controller have switched
off the pump runs for an additional 3
minutes for boiler protection
OFF - Disables pump over run. When
all controller are switched off the
pump will also switch off immediately
as well

- Pump and Boiler Delay
This can enable boiler and pump protection, for instance it delays
the turn on time for pump and boiler by three minuites after an
sensor calls for heat if required this function can be de activated
using jumpers shown
