Introduction

The controller is designed to control CH and HW pumps. CH pump turns
ON when boiler temperature exceeds user setpoint temperature. HW
pump work depends on the temperature difference. HW pump turns
on when boiler temperature exceeds the temperature of the tank by
hysteresis value set by user. HW pump works until the temperature of
the boiler and the temperature of the tank will be equal or setpoint
temperature of the tank will be achieved.
